Color

To understand blend modes, you need to know a little about color. Color is light, and likewise, light is made up of many colors. Objects absorb or reflect these light waves. Our eyes perceive these wavelengths as color. Let’s start with the color wheel.

The COLOR WHEEL has 12 segments that consist of primary, secondary and tertiary hues, or colors.

The three PRIMARY colors are RED, YELLOW, and BLUE. They form a triangle on the wheel. These colors cannot be mixed by combining any other colors. They are indicated on the color wheel with a P.

The three SECONDARY colors of ORANGE, VIOLET, and GREEN (marked on the chart by an S) are created by mixing equal parts of the primary colors they fall in between; ie, VIOLET is the secondary color produced by mixing equal parts of RED and BLUE.

The TERTIARY colors are the colors that result from mixing the primary and secondary colors on either side of them: ie, mixing the secondary color ORANGE with the primary color RED results in red-orange. These colors are marked on the color wheel with a T.

Using the color wheel you can determine color schemes fpr balance and harmony in your artwork, webpages, desktop publishing designs or home decorating.

Luminosity, or Lightness: A measure of the amount of light reflected from a hue. Those hues with a high content of white have a higher luminance, or value. Continue reading →
