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
