The Unison Color Theory

Many manufacturers assign names to colors. Unison has chosen instead to assign color designations based on the value grouping the color belongs to. For example, Unison offers a Red Value Range of 18 colors and a Red Earth Range of 18 colors. White can be found in the grey range (Grey 28). Black is also found in the grey range (Grey 36).  

The original Unison line consisted of 234 colors which were divided into 13 value groups, each with 18 colors. Since that time, Mr. Hersey has brought the number of Unison colors to 372. To assist you in your search, we have posted color charts for all of the colors based on their value groups, not by their item number. 

Please remember when viewing the on-line color charts, that colors will vary from monitor to monitor, and should only be used as a general reference tool. Printed and handmade color charts using actual Unison colors can be ordered from your favorite Art Supply Dealer.
