Complimentary Color Banner

This is meant as a banner design, unfortunately the proportions are off, but you can still see the color ideas at work. Complimentary colors are directly across from each other on the color wheel, and in their opposite nature they intensify each-other.

Subtractive Color Wheel

As the title tells you, this is a subtractive color wheel, which means that it represents the colors produced by mixing pigments which reflect certain colors of light. The three primary colors, those which we cannot attain by mixing other colors are Red, Yellow and Blue. When we mix two of these evenly, we wind up with the secondary colors: Violet, Orange and Green. Mixing a primary color and a secondary color creates a terciary color (the six visable on the wheel that are left.)

Round the outside of the wheel the shapes you see are pure colors. In the inner rings you see lower intensity variations: from the outside in you see tints, tones, and shades. A tint is a color mixed with white, a tone is acolor mixed with grey, and a shade is a color mixed with black.

Inventive Grayscale Design

Here, the greys are not in sequence, but each of the eleven gradations from black to white are shown.

Grayscale Sphere

This shows how variations in value can create the illusion of depth, as the superimposed circles theoretically become round out to become a sphere.

This shows the Munsell scale for value (darkness/lightness). As the greys absorb rather than reflect more light they appear darker. The Metaphor of sound, with is often used for color, is used here with darker greys being referred to as low key and lighter greys as high key.
