Abstract
Abstract Apparatus and method for color selection comprising apparatus defining a color display and selection space including a first area in which colors of a range of different hues are displayed at substantially predetermined levels of luminance and saturation and a second area in which colors of a selected hue, selectable from said range of different hues, and of differing saturation and luminance are displayed.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
62 words
Apparatus for color selection comprising: means defining a color display and selection space including a first area in which colors of a range of different hues are displayed at substantially predetermined levels of luminance and saturation and a second area in which colors of a given hue, selectable from said range of different hues and of differing saturation and luminance are displayed.
Claim 2
Dependent Claim
62 words
Apparatus for color selection comprising: means defining a color display and selection space including a first area in which colors of a range of different hues are displayed at substantially predetermined levels of luminance and saturation and a second area in which colors of a given hue, selectable from said range of different hues and of differing saturation and luminance are displayed.
Claim 3
Dependent Claim
21 words
Apparatus according to claim 1 and wherein in said first area said colors are displayed in at least one one-dimensional grid.
Claim 4
Dependent Claim
32 words
Apparatus according to claim 2 and wherein said at least one one-dimensional grid is operative to display said colors at a relatively low resolution and at uniform levels of luminance and saturation.
Claim 5
Dependent Claim
30 words
Apparatus according to either of claims 2 and 3 and wherein said at least one one-dimensional grid is operative to display said colors covering the full available range of hues.
Claim 6
Dependent Claim
52 words
Apparatus according to any of claims 2 - 4 and wherein said at least one one-dimensional grid comprises a plurality of one-dimensional grids including also a one-dimensional grid which displays at relatively high resolution a relatively limited range of hues about a selected hue generally at selected levels of luminance and saturation.
Claim 7
Dependent Claim
23 words
Apparatus according to any of claims 1 - 5 and wherein in said second area said colors are displayed in a two-dimensional grid.
Claim 8
Dependent Claim
25 words
Apparatus according to any of the preceding claims and wherein in said second area, variations in saturation and luminance are displayed along mutually orthogonal axes.
Claim 9
Dependent Claim
44 words
Apparatus according to any of the preceding claims and wherein in said first and second areas, colors are displayed in color blocks and wherein the color of each color block is a central color of a range of colors represented by said color block.
Claim 10
Dependent Claim
27 words
Apparatus according to claim 8 and wherein the selection location of a color within a color block defines which color of said range of colors is selected.
Claim 11
Dependent Claim
38 words
Apparatus according to any of the preceding claims and also comprising means for selection of a pair of colors, a first color constituting a constant reference for a second selectable color displayed in said first and second areas.
Claim 12
Dependent Claim
46 words
Apparatus according to any of the preceding claims and also comprising areas for the display of a reference color and a selected color said reference color being selected from an image on the screen and said selected color being the color to replace said reference color.
Claim 13
Dependent Claim
97 words
A color selection method comprising the steps of: defining a color display and selection space including a first area in which colors of a range of different hues are displayed and a second area in which colors of a given hue, selectable from said range of different hues, and of differing luminance and saturation are displayed; iteration in any order of the following mutually independent operations: a. for given luminance-saturation levels, selecting a given hue from the first area; and b. for a given hue, selecting a color of given luminance and saturation from the second area.
Claim 14
Dependent Claim
97 words
A color selection method comprising the steps of: defining a color display and selection space including a first area in which colors of a range of different hues are displayed and a second area in which colors of a given hue, selectable from said range of different hues, and of differing luminance and saturation are displayed; iteration in any order of the following mutually independent operations: a. for given luminance-saturation levels, selecting a given hue from the first area; and b. for a given hue, selecting a color of given luminance and saturation from the second area.
Claim 15
Independent Claim
127 words
A method for selection of two associated colors comprising the steps of: defining a color display and selection space including a first area in which first colors of a range of different hues are displayed against the background of a second reference color and a second area in which first colors of a given hue, selectable from said range of different hues, and of differing luminance and saturation are displayed against the background of said second reference color; selecting a reference color; varying said first color iteratively in any order of the following mutually independent operations: a. for given luminance-saturation levels, selecting a given hue from the first area; and b. for a given hue, selecting a color of given luminance and saturation from the second area.
Claim 16
Independent Claim
127 words
A method for selection of two associated colors comprising the steps of: defining a color display and selection space including a first area in which first colors of a range of different hues are displayed against the background of a second reference color and a second area in which first colors of a given hue, selectable from said range of different hues, and of differing luminance and saturation are displayed against the background of said second reference color; selecting a reference color; varying said first color iteratively in any order of the following mutually independent operations: a. for given luminance-saturation levels, selecting a given hue from the first area; and b. for a given hue, selecting a color of given luminance and saturation from the second area.
Claim 17
Dependent Claim
18 words
A method according to claim 13 and also comprising the steps of interchanging the first and second colors.
