1. A method for selecting a color palette, comprising:
- receiving a feature from an image of an object and a calibrated reference color chart, the calibrated reference color chart including reference colors and selected from among a plurality of reference charts;
calculating a transform to correct a color in the calibrated reference color chart within the image to be coordinated with or to be the closest matching shade to a corresponding reference color;
correcting a color in the feature using said transform; and
from a plurality of color palettes, each color palette comprising a plurality of complementary colors, selecting the color palette having a color that most closely matches the corrected feature color.

Abstract
A method for selecting a color palette includes receiving a feature from an image of an object and a reference color chart, calculating a transform to correct a color in the imaged reference color chart, correcting a color in the feature using the transform, and selecting a color palette based on the corrected feature color. The reference color chart includes reference colors, and the transform corrects the color in the imaged reference color chart to substantially equal a corresponding reference color. An apparatus for selecting a color palette is also described.

11. A method for selecting a color palette, comprising:
-
extracting color-corrected pixels; minimizing a color difference between said color-corrected pixels and a database of finish samples to find the closest matching finish; and from a plurality of sets of complementary finishes, selecting the set of complementary finishes that has a finish most closely matching the closest matching finish. - View Dependent Claims (12, 13)

14. An apparatus for selecting a color palette, comprising:
-
a color corrector for receiving a feature from an image of an object and a calibrated reference color chart, the calibrated reference color chart including reference colors and selected from among a plurality of reference charts, calculating a transform to correct a color in the reference color chart within the image to be coordinated with or to be the closest matching shade to a corresponding reference color, correcting a color in the feature using said transform, and generating a corrected feature color; and a palette selector for selecting, from a plurality of color palettes that each comprise a plurality of complementary colors, the color palette having a color that most closely matches the corrected feature color. - View Dependent Claims (15, 16, 17, 18, 19, 20)
