How important is hair, eye, and skin color when it comes to building outfits? What's the most important?
Through cursory online research I have determined that I have warm undertones because my veins look greenish and I tan easily or whatever. I have brown hair and hazel eyes.

According to this image and others like it, am I better off throwing out all my raw denim? Who can wear black and white and grey? Nobody or everybody?
Doesn't this contradict the suggestion that you should wear colors that contrast with your eyes (for me that would be violet)?
Should I sell my silver watch and get a gold one?

I have money to spend and want to improve my wardrobe but I don't know what I'm doing color-wise.

Does anyone know what I'm talking about?
