Color blending set and paint mixing tray
Abstract
Abstract A color mixing tray which is a planar member with a plurality of wells arranged in an annular pattern. There are a plurality of wells in each of a plurality of sectors of the annular pattern, with wells in each sector radially spaced and each well in each sector having a counterpart in the other sectors. The counterpart wells of the sectors are in an annular ring within the annular pattern. Each well is separated from each other well by a wall and the walls between the wells within each sector are lower in height than the walls between the wells in adjacent sectors to facilitate transfer of paint between wells within a sector while maintaining isolation from sector to sector. A color mixing set combines the mixing tray with a supply of paints of mixing hues in balanced primary colors and in black and white, each paint supply being in a container having provision for dispensing measured quantities of paint therefrom. The set further includes a student guide having a spectrum chart representing the wells of the mixing tray together with indicia indicating the location of and providing instructions for mixing of the red, yellow and blue colors to create secondary and intermediate colors and for the mixing of the colors with each other and with the black and white paints to create shades, tints and tones.
