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.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 241 words
A color mixing set for use by a student in applied color mixing experimentation, to demonstrate in a coordinated manner the principles of primary, secondary and intermediate colors, shade, tint and tone color variations and the hue, value and intensity color dimensions, said set comprising: a planar mixing tray member having a plurality of wells therein arranged in an annular pattern, there being a plurality of wells in each of a plurality of sectors of said annular pattern, the wells in each sector being radially spaced, each well in each sector having a counterpart in the other sectors, the counterpart wells being in an annular ring within the annular pattern, each well being separated from each other well by a wall; a supply of mixing paints in each of the primary colors, red, yellow and blue, and in white and black, each paint supply being in a container with provision for dispensing measured quantities therefrom; and a student guide having displayed thereon a spectrum charge with a representation of the wells of the mixing tray, indicia indicating the relative locations of the primary, secondary and intermediate colors, indicia for the mixing of the red, yellow and blue colors to create the secondary and intermediate colors, further indicia for the mixing of the colors with each other and with the white and black paints to modify the hue, value and intensity of the colors and to create shades, tints and tones thereof.
Claim 2
Dependent Claim 241 words
A color mixing set for use by a student in applied color mixing experimentation, to demonstrate in a coordinated manner the principles of primary, secondary and intermediate colors, shade, tint and tone color variations and the hue, value and intensity color dimensions, said set comprising: a planar mixing tray member having a plurality of wells therein arranged in an annular pattern, there being a plurality of wells in each of a plurality of sectors of said annular pattern, the wells in each sector being radially spaced, each well in each sector having a counterpart in the other sectors, the counterpart wells being in an annular ring within the annular pattern, each well being separated from each other well by a wall; a supply of mixing paints in each of the primary colors, red, yellow and blue, and in white and black, each paint supply being in a container with provision for dispensing measured quantities therefrom; and a student guide having displayed thereon a spectrum charge with a representation of the wells of the mixing tray, indicia indicating the relative locations of the primary, secondary and intermediate colors, indicia for the mixing of the red, yellow and blue colors to create the secondary and intermediate colors, further indicia for the mixing of the colors with each other and with the white and black paints to modify the hue, value and intensity of the colors and to create shades, tints and tones thereof.
Claim 3
Dependent Claim 16 words
The color mixing set of claim 1 in which said student guide is a wall chart.
Claim 4
Dependent Claim 21 words
The color mixing set of claim 1 in which said student guide is an instruction sheet used individually by the student.
Claim 5
Dependent Claim 45 words
The color mixing set of claim 1 in which said mixing tray includes a further series of wells, separated by walls, for mixing the white and black paints in differing proportions in each of the series of wells to create a set of gray values.
