I wish I could figure what appeals to most individuals and have it on hand. I realize we all have different tastes, likes and dislikes, but when you are making a common product it is hard to gauge color schemes.
I could start with the seasons; darker colors for Fall and Winter and pastels and sunny colors for Spring and Summer. There is still no guarantee that what you make will sell. My dilemma is no matter how much people love what I make, they want something other than what I have.
