Continuation: lightfastness chart photos

Thinking back on it, maybe it would have been best to delay gratification and combine this post and the last, into one. 🙂 In any case, I do now have photos.

I used Photoshop to cut out the two empty rows on the left, between the reds and blues.

I’ve opted for a more natural look to this, instead of trying to make the white of the paper as close as possible to the white of the screen, which distorts the colors a bit. There is a brightness adjustment added to this, but that’s all.

I’ll be identifying the colors by Row (top to bottom) and Column (left to right), for my international readers…I realize this might not be immediately apparent.

I also need to let you know a bit of errata: Viridian (Row 4, Column 5) isn’t a cobalt color, it’s a chromium color. I have a pattern of confusing one for the other…

Last night, I was also mistaken in saying that Vermilion Deep was the only paint in which I got brush strokes: Raw Umber (Row 3, Column 6) did it too, but I don’t expect much from Raw Umber, at this point (maybe I should try a different brand).

Anyhow: see that Winsor Orange (Row 2, Column 4)? Gah. It’s just terrible compared to the majority of the colors. Because my Winsor Orange tube also has a cracked cap and wanted to gush when I tried getting the cap off the tube (it was stuck and I had to really work to get it off)...and it grays out really quickly once I try to mix it…I’m not entirely certain what I’m going to do with it. Maybe I’ll go to an artists’ meetup and conveniently forget it/donate it…

blue test swatches

This time, swatching out the blues did produce an effect that is visible on a computer monitor (…I think?). Some of these colors, though…

I was working wet-into-wet, here. With a fully loaded brush, sometimes the paint dispersed immediately to leave the area I intended to mark heavily, leaving mid-range coverage in its wake. With some paints, like Cobalt Blue (second from the top, to the left), the paint actually seemed to try to cover the entire area evenly, instead of in a gradation. This would be a good thing if you were using it for a sky, which this color is almost perfect for (unless you didn’t want a blue sky!).

I had been trying to produce gradations to see what finer applications of the colors might do under sunlight.

One of the things I am impressed with, though, is the beauty of the colors which are more muted, here. I think I started out in class with French Ultramarine, Cobalt Blue, and Phthalo Blue (Green Shade). Cerulean Blue Chromium, Prussian Blue, and Indanthrene Blue were all later additions.

I’ve mentioned before that I read on that indanthrene/indanthrone can be approximated by a mix of Phthalo Blue with Quinacridone Violet (a.k.a. Permanent Magenta, in Winsor & Newton’s range: Row 6, Column 1) — check the notes under PB60 (Pigment Blue 60). I’ve tried this, and it does work, though the mix is obviously going to vary in shade depending on proportions.

I can also see myself working with Prussian Blue more, in the future. I believe I got this to try and mix decent greens…with my memory being unclear on whether it actually helps, though I think it does.

swatches of red paints

To the right, here, are the reds I’ll be testing. The relative character of Permanent Rose does, I think, come through — though this is still a bit of a dull capture. I’m looking at it now under an artificial light and it seems to almost glow. (This is Winsor & Newton’s formulation: different companies have a tendency to call the same pigments by different names.)

The top two, Rose Madder and Alizarin Crimson, are known to change color over time; hence they’re called fugitive pigments. I’m doing the lightfastness test to see how bad this actually is.

Incidentally…those two colors are related. They were originally derived from Madder (a plant) — Alizarin Crimson is one of two components that make up its color…

Anyway, the top swatch is Mijello Mission Gold — I got it as a bonus when I bought my palette. But even here, they acknowledged that it is not great so far as longevity…The second swatch, Alizarin Crimson, is Winsor & Newton brand. I’m not crazy about it, when there are alternatives.

I really like the Winsor Red (fourth from the top), after all this time. This was our “warm” red in Watercolor class (using a split-primary palette), though it barely leans to either a warm or cool direction. (Permanent Rose was our cool red.)

I’m not sure what to do with Vermilion Deep, though as I said last post, I’m going to try and find a better-quality paint. This one had almost no flow, and I’m not sure if it’s due to age (I got it on Amazon, who knows how old it is) or formulation. Maybe the page was just too dry?

Permanent Magenta isn’t showing up in the photograph, all that well…but I just checked another file and it’s similarly distorted. Permanent Magenta is basically a red-leaning violet color, more than a violet-leaning red. There’s an earthiness that it shares with Indanthrene Blue, which one might expect…

When mixing two pigment colors — like Permanent Magenta and Phthalo Blue (excluding fluorescent colors [which absorb light and re-emit it at different wavelengths], duochrome paints [which look different depending on one’s viewing angle] and complex things like dichroic glass [which both transmit and reflect light, though this may be an entirely different animal]) — the result of the mix reflects frequencies of light that have to be reflected by both (?) of the colors which went into it, unless I’m mistaken.

The basis of subtractive color (as used in non-digital painting) is that we perceive color as the leftovers of the light absorbed. The frequencies of reflected and emitted light, taken together, our brains interpret as a specific color. So Permanent Magenta reflects many wavelengths (colors of light), which my brain interprets as predominantly warm violet, with red. And Phthalo Blue reflects many wavelengths, which my brain interprets as deep blue with a hint of green.

When pigments are mixed, what is left over after both pigments subtract what they will of the light present, is the new color. In other words, a color very close to Indanthrene Blue is the light which was not absorbed by both Permanent Magenta and Phthalo Blue. Magenta absorbs some of what Blue doesn’t; Blue absorbs some of what Magenta doesn’t.

The forward result is a deep, inky blue with both violet and green tones supporting it, closer to black (black means no light is reflected), which makes sense…though I’m not sure I could do the math now to support why I think it does make sense. The following is just hypothetical:

On a scale from white (100%) to black (0%) — we’re talking about value, now —

Some light is subtracted from 100% with Magenta (Magenta would have a negative value); and more light is subtracted with Magenta + Blue (Blue would also have a negative value; the addition of a negative value is the same as subtraction). Even though this is not simple subtraction (after all, we are talking about many, many frequencies of light which are being tweaked individually), if Black = 0% and both Magenta and Blue subtract their part from 100% (white light), it seems feasible to state that:

close up of Permanent Magenta, Phthalo Blue, and Indanthrene Blue in greyscale

Magenta + Blue < Magenta, and

Magenta + Blue < Blue.

Wow, that was hard to get out. And I might be wrong, or maybe I should go into Chemistry + Optics…

There is the remaining fact that my Phthalo Blue swatch is indeed darker than my Indanthrene Blue swatch. I’m thinking that this has to do largely with the density of its application, not to mention the intensity of Phthalo Blue pigment, which has to be severely diluted to get to the point where we can even see that it’s blue. I do see that Indanthrene is grayer, though, and I wonder if that matters…

I’ve just looked at the image in greyscale, but I’m not sure that helps…

It doesn’t help, either, that my camera didn’t totally pick up the intensity of the Phthalo Blue application. I’m not sure why.

To get back on track, then…there are the yellows. I kind of am irritated at myself for not planning their placement out better, and it’s to the point that I don’t want to cut them out and rearrange them on Photoshop. But if you scroll back up to the top of the page, or better yet, if I re-post that image below:

…you can see that Isoindoline Yellow Deep (PY110), Indian Yellow (PO62, PY139 — just realized that this is a mix of Winsor Orange [!] and a different variant of Isoindoline Yellow), Winsor Yellow Deep (PY65) all look very similar.

For the cool yellows, Winsor Yellow (PY154), Hansa Yellow (PY3), and Aureolin (PY40) are hard to tell apart, here: but it’s not so bad in person — at least, when the sun is up!

Then there are the oranges, neither of which I’m too fond of, but Cadmium Orange Hue did save me from having to mix orange from the limited pigments we were allowed, in Watercolor class. It’s possible that the intensity of Cadmium Orange just can’t be gotten out of the colors we had. Maybe I should stop looking toward the yellows for the source of the problem, and try mixing more with an orangish, warm red, instead of a middling red.

At Green Gold (Row 3, Column 4), the yellows start morphing into greens. I feel the need to suggest that perhaps what I had mentioned before about mixing an alternative in acrylics from Bronze Yellow + an Earth Yellow + a blue, may have been off point. You see, Green Gold doesn’t look like it’s meant to be used on its own, but rather sparingly, to do things like warm up greens. It looks fairly horrific on its own and in high density, but look at this:


This is something I was playing with, a while back (hence the example number, I just pulled this from my archives): apologies for the lack of realism (it wasn’t the point of this exercise). Green Gold is what I used to heat up the right side of that leaf. It’s also transparent, so it’s very suited for this.

I don’t think that a mixture approximating what one sees in the tube or applied heavily, really gets close to what one would use Green Gold for. As I said a while back, Green Gold is a very expensive pigment. But I can see that a little goes a long way.

It wouldn’t have come to me so soon, except that in my latest play, I rinsed the Green Gold watercolor paint off of my palette and saw it form an almost neon yellow-green color in high dilutions in the sink. This isn’t something that’s meant to be used as-is, but rather combined with other colors.

I also really want to get into trying to mix more greens, so I can stop dealing with the question of how to create a yellow-leaning green. This is part of why I got Sap Green, unless I’m mistaken (I think the only green we were allowed in class was Viridian…which at the time, I hated. Not so much, now).

Speaking of Viridian, I’ve been advised not to let it dry long-term on a palette. I took this advice and kept it out of my Mijello palette; however, this also means that it goes forgotten, a lot of the time. But I don’t want it to become like Burnt Umber and just become a free-floating rock whose composition I have to guess at. (Burnt Umber still rehydrates beautifully; it just rattles around as — well — a rock, in dry form.)

three granulating green to green-blue pigments

I have an appreciation for Cobalt Turquoise now, that I don’t think I could have predicted. These two colors — Cobalt Turquoise and Cobalt Turquoise Light — are heavily granulating colors. I’m not sure if I’ve played with them too much, but the three pigments to the right are ones that are relatively intriguing for me, right now.

Particularly, it may be possible to get a more vivid range of greens by starting with a lighter-valued intense pigment like Cobalt Turquoise Light.

Also: Indigo and Payne’s Grey…are two colors that kind of wow me, now. Payne’s Grey is a cool-toned color which is almost, but not quite, black. If black brackets one end of a color range, Payne’s Grey would sit between it and Indigo.

The Indigo color I have is Winsor & Newton, and it isn’t actually true indigo dye (as real indigo is fugitive, this being why jeans fade).

Aside from this, I feel the need to mention, if briefly, Dioxazine Violet (Row 2, Column 5)…which is probably not a necessary color on this palette, now.

Earth tone paint swatches

And the entire column to the left of this passage, including Payne’s Grey, is composed of earth tones. The only one of these that I’m questioning the utility of is Raw Umber, because what I’m seeing in my photos and on my paper is what I’d consider, fairly…well, bad. I’m not sure if it’s me or the paint, or the amount of water on the paper…but I think it’s the paint. This is Winsor & Newton, as well.

The thing about Raw Umber is that I’ve been looking at paint swatches of different brands online, and they don’t all look alike. I’m not entirely sure…what causes that? but there are definitely versions which are bluer than others. In Color Dynamics class, we made a mixture of Ultramarine plus Raw Umber to produce a blend which could dull down colors without causing them to lose their essential character (or “hue,” if you would like me to be direct). 🙂

And in Watercolor class, we didn’t even use earth tones; we mixed them by utilizing a strategy of mixing across the color wheel (as I’ve mentioned [somewhere] before, this will result in muted colors, ranging into chromatic greys). I’m really not sure if anyone liked doing it. 😉 But earth pigments are a nice shortcut if you don’t want to mix skin tones out of three primaries. 😛

The nice part about mixing watercolors is that if you use a white palette, you can see what color you’re coming up with before you ever put it on the paper (though that can’t always be exactly accurate — I’ve seen artists online make test marks on the edges of their drawings. I used to make test marks on the facing pages of the sketchbooks…).

After all of that — unless my light, here, has already faded some of this, I should be moving on to putting black strips over the faces of the swatches. I’m probably also going to be doing some cutting in the process…which will likely be at least a little nerve-wracking, because I haven’t completely gotten the hang of not having my knife veer off course, yet!

Anyhow, that’s for another day…
