Method and apparatus for color selection and production

Claim 2

Apparatus for selecting a color as a function of a first set of color characteristics for implementation as a function of a second set of color characteristics, said apparatus comprising means for generating a first display indicative of values of --one color characteristic included in said first set; means for selecting a value of said displayed one color characteristic; means for generating a display indicative of interaction of values of another color characteristic included in said first set with said selected value of said one color characteristic; means for selecting a value of said displayed other color characteristics; means for converting said selected values to values of said second set of color characteristics defining said color; and means for implementing said color as a function of said second set of color characteristics. -

Claim 3

Apparatus according to claim 1, including means for generating a display indicative of interaction of values of a third color characteristic included in said first set with the selected values of said first and second color characteristics; and means for selecting a value of said third color characteristic.

Claim 4

Apparatus according to claim 1, including means for generating a display indicative of values of a third color characteristic included in said first set; and means for selecting a value of said displayed third color characteristic.

Claim 5

Apparatus according to any of claims 1 to 3 wherein said one color characteristic has a range of values, and said first display means generate a display indicative of said range of values.

Claim 6

Apparatus according to any of claims 1 to 3 wherein said one color characteristic has a range of values, and said first display is indicative of a portion of said range of values.

Claim 7

Apparatus according to claim 5 including means for scrolling said first display so as to provide a display indicative of an additional portion of said range of values.

Claim 8

Apparatus according to claim 1, further comprising means for converting said selected values to values of said third set of color characteristics defining said color; and means for implementing said color as a function of said third set of color characteristic.

Claim 9

Apparatus for the production of a representation of color as a function of a first set of color characteristics of hue, saturation and brightness for implementation as a function of a second set of color characteristics, said apparatus being arranged to provide (1) generation of a display indicative of values of hue; (2) selection of a value of hue; (3) generation of a display indicative of interaction of values of saturation with said selected value of hue; (4) selection of a value of saturation; (5) selection of a value of brightness; (6) conversion of said selected values to values of said second set of color characteristics defining said color; and (7) production of said representation of said color as a function of said second set of color characteristics. 9. Apparatus according to claim 7, the apparatus being further arranged to provide a display indicative of values of brightness.

Claim 10

A computer graphics system for providing selection of a color as a function of hue, saturation and brightness and the display of the color as a function of red, green and blue, the system being characterised by the combination of means for generating a first display indicative of values of hue; means for selecting a value of hue; means for generating a second display indicative of interaction of values of saturation with said selected value of hue; means for selecting a value of saturation from said second display; means for generating a third display indicative of values of brightness; means for selecting a value of brightness; means for converting said selected values of hues, saturation and brightness to values of red, green and blue; and means for displaying said color as a function of red, green and blue.

Claim 11

A computer graphics system for providing selection of a color as a function of hue, saturation and brightness and the display of the color as a function of red, green and blue, the system being characterised by the combination of means for generating a first display indicative of values of hue; means for selecting a value of hue; means for generating a second display indicative of interaction of values of saturation with said selected value of hue; means for selecting a value of saturation from said second display; means for generating a third display indicative of values of brightness; means for selecting a value of brightness; means for converting said selected values of hues, saturation and brightness to values of red, green and blue; and means for displaying said color as a function of red, green and blue.

Claim 12

A system according to claim 10 in which the third display indicates the interaction of the values of brightness with the selected values of hue and saturation.

Claim 15

A method according to claim 12 including the additional steps of generating a display indicative of interaction of values of a third color characteristic included in said first set with the selected values of said first and second color characteristics; and selecting a value of said displayed interaction of values of said third color characteristic.

Claim 16

A method according to claim 12, including the additional steps of generating a display indicative of values of a third color characteristic included in said first set; and selecting a value of said displayed third color characteristic.
