1. A system comprising:
- a processor; and
a machine-readable storage device including instructions operable to cause the processor to provide a color chart for presenting color samples, the color chart comprising;
an arrangement of a plurality of color samples, each color sample representing a distinct color and having a colored area filled with a corresponding color in a color space;
one or more color identifiers associated with each color sample in the arrangement, the one or more color identifiers associated with each color sample having one or more values uniquely identifying the color represented by the corresponding color sample; and
a gamut identifier identifying a color gamut relative to the colors represented by the color samples in the arrangement where the identified color gamut defines a range of colors and respective color samples that cannot be reproduced by a first device and where the gamut identifier identifies a plurality of colors, represented by two or more color samples of the plurality of color samples in the arrangement, that are outside the identified color gamut.

Abstract
Methods and apparatus, including computer program products, for presenting color samples in a color chart. The color chart includes an arrangement of multiple color samples that include colored areas representing colors in a color space. Color samples in the arrangement are associated with one or more color identifiers that uniquely identify the colors represented by the corresponding color samples. A gamut identifier identifies a color gamut relative to the colors represented by the color samples in the arrangement. A gamut mapping is provided to map a color from outside the color gamut to a color inside the color gamut.

18. A computer-implemented method for representing colors in a color space, the method comprising:
-
arranging a plurality of color samples in a color chart, each color sample representing a distinct color and having a colored area filled with a corresponding color in the color space; displaying one or more color identifiers with each color sample in the color chart, the one or more color identifiers associated with each color sample having one or more values uniquely identifying the color represented by the corresponding color sample; and displaying, using a display device, a gamut identifier representing a color gamut relative to the colors represented by the color samples arranged in the color chart where the color gamut defines a range of colors and respective color samples that cannot be reproduced by a first device and where the gamut identifier identifies a plurality of colors, represented by two or more color samples of the plurality of color samples in the arrangement, that are outside the identified color gamut. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28)

29. A machine-readable storage device tangibly embodying a computer program for representing colors in a color space, the computer program including instructions operable to cause a data processing apparatus to:
-
arrange a plurality of color samples in a color chart, each color sample representing a distinct color and having a colored area filled with a corresponding color in the color space; display one or more color identifiers with each color sample in the color chart, the one or more color identifiers associated with each color sample having one or more values uniquely identifying the color represented by the corresponding color sample; and display a gamut identifier representing a color gamut relative to the colors represented by the color samples arranged in the color chart where the color gamut defines a range of colors and respective color samples that cannot be reproduced by a first device and where the gamut identifier identifies a plurality of colors, represented by two or more color samples of the plurality of color samples in the arrangement, that are outside the identified color gamut. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36, 37)

38. A system comprising:
-
means for arranging a plurality of color samples in a color chart, each color sample representing a distinct color and having a colored area filled with a corresponding color in the color space; means for displaying one or more color identifiers with each color sample in the color chart, the one or more color identifiers associated with each color sample having one or more values uniquely identifying the color represented by the corresponding color sample; and means for displaying a gamut identifier representing a color gamut relative to the colors represented by the color samples arranged in the color chart where the color gamut defines a range of colors and respective color samples that cannot be reproduced by a first device and where the gamut identifier identifies a plurality of colors, represented by two or more color samples of the plurality of color samples in the arrangement, that are outside the identified color gamut. - View Dependent Claims (39, 40, 41, 42, 43, 44, 45, 46, 47)
