Does the color of a room affect your skin temperature?

No, the color of a room does not directly affect your skin temperature.

However the colors of a room could suggest to you that it is warmer or colder than it is - red walls might suggest warmth and brilliant white is said to be cool so ther could be a small phychological effect.

Also, if there is bright sun-light streaming into the room the color of the wall could affect the amount of energy (heat) absorbed by the walls or refelcted back out of the room - dark colours absorb energy, light colors absorb less. The effect may be too small to make a tangible difference to the air temperature but there would be some.
