  We present a simple primary colour editing method for consumer product
images. We show that by using colour correction and colour blending, we can
automate the pain-staking colour editing task and save time for consumer colour
preference researchers. To improve the colour harmony between the primary
colour and its complementary colours, our algorithm also tunes the other
colours in the image. Preliminary experiment has shown some promising results
compared with a state-of-the-art method and human editing.
