Colour

I am using 5 colours for shoes. I want to use more but buyers normally have no idea what they should buy. I mean, They can imagine only traditional colours such as bluck,brown, baige and navy. So if I have many colours, I will not use colours except traditionals. That is no meaning to keep and loss profit. Recently I have an idea to put colours on leathers of my stocks. even if someone requires radical image, I will be able to accept it!
