Blue would be that color because blue seems to enhance creativity and blue is spiritual. The Native Americans where I live most have their front doors painted blue in order to help keep evil spirits away.
I like a navy blue, but not to navy, may be like a royal type blue but not like purple though, so i guess it would be more like a mix of turquoise and a navy blue, but an orginal blue is good to with a hint of turquoise. What im trying to say is the I like red.....no haha jk Blue is my fave...but red is cool too...in moderation
