Thanks for asking, but it's a strange question.
Could you please define or describe what you consider real colors" ?

Just a quick reply for now: people always refer to "gold" or "copper" as a color, while in fact it's more than just a color. It's the typical reflection that makes us perceive it as a specific material (like certain metals). Is that what you meant ?
