The updated Quantcast color palette has 5 tiers of colors, to be used for different purposes, as outlined below.
Our Primary colors are the colors that will be used most often in creating new documents or brand materials.
Our secondary colors act as small accent colors to our primary colors (eg. links and buttons).
Our flood colors surround and coordinate with our core patterns, and should be used as backgrounds to break up large expanses of white on the web and in presentation documents. When used as a background, these colors should be used with white type.
Our highlight colors are used as background colors for our core patterns.
Our shadow colors are used as shadow and accent colors within our core patterns.
