Skin colour has a potential connection to facial impressions. For CG (computer graphics) character designing, tuning the skin colour to build a required character is a vital procedure. The previous findings provide essential suggestions to build an attractive face, but are still insufficient for the Artificial Intelligence (A.I.) system to build characters with different personalities and impressions. The present study investigates the relationship between skin colour and multiple categories of impression attributes based on a psychophysical experiment. Four attributes, which represent 23 attributes from personality and impression, were selected based on the principal component analysis. The relationship between these attributes and the hue angles was demonstrated which can be used to guide the AI system for character designing.
