Colour perception is also related to experience. For example, the colour orange did not exist in the European vocabulary until the 11th century when the Arabs imported the "fruit approved by elephants", naranj. Prior to that, Europeans referred to the colour as an "ugly red".
An experiment was done with Inuit people decades ago which had them place similar-colored cards into piles. Sure enough, the cards we would consider orange, were either stuck in the red or yellow pile. Their eyes could perceive the hue of orange but the lack of a distinct word, had them randomly adding it to the "blood" or "sun" pile.
