I. INTRODUCTION
transfer colors according to preference
11 basic color categories (BCCs)
black, white, gray (the achromatic ones),
red, green, yellow, blue, brown, purple, orange, and pink (the chromatic ones)

II. OUR APPROACH
A. Handling the Illuminant Color in Images
D65 The color-by-correlation method
B. Color Naming Method two steps: initial color naming fuzzy color naming

II. OUR APPROACH
previous work: cluster the space
into 11 BCCs
11-D vector

II. OUR APPROACH
C. Computing Corresponding Color Values in the Chromatic Categories
basic convex hull
