Colour Palettes (development of characters)

Colour is everywhere and helps visually describe many elements in everyday life and is an importance in animation, colours help to understand feelings and personalities, a character displays.  Understanding character roles, helps understand how the character is represented by colour, Ying and Yang is an example that demonstrates good and bad which I'm trying to incorporate into my character designs.

Many characters are being made and can be depicted wrong because of the colours used, this Article demonstrates what colours are used for different character types, placing them in good/bad category. 

I naturally choose colours already associated with my characters, being a goldish brown for my hero and a dark purple for my villain, as seen in this character design:

I've also taken the advantage of colour with my narrative backstory where I have created a concept that has an in-between colour symbolising the relationship of both characters in the past.
