Tertiary Colors— are colors made by combining a secondary color with a primary color. There are six tertiary colors. (They are yellow-ish orange, red-ish orange, red-ish purple, yellow-ish green, blue-ish green and blue-ish purple.)

Complementary Colors— Two colors that are on opposite sides of the color wheel. This combination provides a high contrast and high impact color combination – together, these colors will appear brighter and more prominent. The bottom line is for example, if your call-to-action button [Save] is blue or blue background, then white text is a good choice because of high contrast. (The adjacent button may say "Cancel" or "Edit" and that button might have white background with blue stroke or border and blue text.)
