EVEN SO - - bear in mind that your color printers print in CMYK - Cyan, Magenta, Yellow, & Black..... whereas the colors you see on your screen are RGB - Red, Green, Blue........ and to confuse you even further the three PRIMARY colors are RYB - Red, Yellow, and Blue.

So you're not going to get "accurate" colors using these tools...... which is why you (through trial and error) calibrate screen works with printers if the material is to be printed...... and stick to web safe colors on the web...... which will still be different from comp to comp due to the settings of the individual monitors and user prefernces............

The color wheel is divided into three categories: primary, secondary, and tertiary. The three primary colors are red, yellow and blue. These colors are considered to be foundation colors because they are used to create all other colors. By combining two of the primary colors, three secondary colors are formed. They are orange, green and violet. The six tertiary colors are made by combining a primary and an adjacent secondary color. These colors are red-orange, red-violet, yellow-green, yellow-orange, blue-green and blue-violet.

Colors are also divided
into cool and warm
categories. The cool
colors are green, blue
and violet. Warm colors
are red, orange
and yellow.

Split complementary
This color scheme uses three colors: any hue and the two adjacent to its complement. (example: red, yellow-green, and blue-green)

 Triadic
This scheme also uses three colors. They are evenly spaced from each other. (example: red, yellow, and blue)

Discordant Schemes
Double complement

This color scheme uses two pairs of comple-ments. (example: yellow and violet, blue and orange)

Alternate complement

This scheme uses four colors: a triad and a complement to one of the hues. (example: red, yellow, blue and violet)

Tetrad

This scheme uses four colors evenly spaced on the color wheel. A primary, secondary and two tertiary colors are used. (example: red, green, yellow-orange, and blue-violet)
