Color and Light: Premixing–Chapter 7

Mixing Color Strings

Color string–prepared paint blobs of a given hue mixed with a palette knife in steps from light to dark. It saves time when you’re painting observationally.

Advantages: It uses less palette surface than free mixing, you can mix generous batches with your palette knife (leaving your brush to be used just for paint application), and it saves times in the long run–you don’t have to keep remixing colors.

Mixing 4-5 value steps should be enough to get the values you need. Have 2-3 light steps, 2-3 shadow steps and blend anything else you need.

Gamut Mapping

Entire group of possible colors for a painting: gamut. (Polygon superimposed over color wheel.) The colors you use in a composition are as important as the colors you leave out.

Composed of subjective primaries (corners), subjective neutrals (the mixture midway between all extremes).

The secondaries of a triadic gamut will be lower in chroma than the primaries. (Halfway point along each side of the triangle is closer to the gray center–more neutral.) This is called saturation cost.

Creating Gamut Masks:

Cut a mask of a gamut shape and place it atop a color wheel. Move it around to create new schemes.

You can choose exactly what colors you want. You can invent and preview different schemes you might not have considered. You’ll have what you need to create a color scheme, and it looks awesome.

Shapes of Color Schemes

Gamuts are polygons. Can be triangles, diamonds, or squares. Triangles are most common shape. Useful one: equilateral triangle shifted to one side of the wheel without overlapping the center at all–an atmospheric triad

Complementary gamut–long diamond stretching across the middle of the wheel.

Mood and accent scheme–most of piece in one part of environment with a separate shape in a complementary color for accent.

Mixing a Controlled Gamut

choose your color, and then make color strings that you’ll use for your entire painting. Premixing helps you stay within your gamut.

Once you’ve mixed your colors and made your strings, remove the tube colors from your palette–they’re not in your gamut.

Color Scripting

In sequential art (like a movie, illustrated book, graphic novel), no color scheme stands alone. Everything needs to flow with what’s around it.

You can plan your color script with the aid of a color wheel and gamut masks. A sudden gamut change signals a change to the audience.

Color and Light: Paint and Pigments (Chapter 5)

Warm Underpainting:

Paint underneath the painting with a wash of a warm color….

It forces you to cover the background with opaques, forcing you to make mixing decisions.

Most helpful for blue/green paintings–the warm bits peeking through make the greens/blues sparkle.

Sky Panels:

Sky panel is a surface prepared with a sky gradation as a base layer for future painting. (Basically, you paint the sky first, and then come back later to paint everything else once the sky is dried.)

Helpful for describing intricate details against a light sky, and when your chief interest is the complex, middle-ground tracery.

You can prepare backgrounds in advance because clear skies are fairly standard and predictable.

Limited Palettes

Go on a color diet! It leads to a more harmonious effect.

This painting was made with only titanium white, pyrrole red, ultramarine blue, and burnt sienna.

3 reasons to do this:

more harmonious, it forces you out of color-mixing habits, and they’re compact and portable.

Make color wheel tests to preview the range of possibilities with a limited palette. Try using one full-chroma color with two weaker colors from across the center of the spectrum.

The Mud Debate

“Beware of Mud”

Some only use primary pigments laid over each other to transparently achieve all other colors. “Overmixing makes color muddy sometimes, especially when more than three colors are used.”

“Mud is a Myth”

Others say there’s no such thing as a muddy color mixture. Either you’ve mixed the right color or you haven’t. The dullness/muddiness comes from poor value organization. It doesn’t matter how you come to achieve a mixture.

Gurney’s opinion: more paintings suffer from the “fruit salad disease” of too much pure color rather than from murky mud. The cure for either problem is good value organization–good planning.
