In order to make tan you should mix white and brown. If you want to make the brown color yourself mix 2 parts of one primary color (like red) and 1 part of each of the other t â¦ wo (blue and yellow). The more white you use the lighter the shade of tan.
Personally, I love gray, it's cool, serene, calm. A wonderful change from years of BEIGE being shoved down our throats. I like cool colors better than warm, so gray appeals to me much more than tan, brown, or beige...the colors of dirt! ;) To each their own though, that's what makes everyone unique!
