Profitable Color Combinations Used In Cover Design
5. Red – black – white
Red and black combined with white create a nice impact to the eye. These covers usually jump into the visitor’s eyes through their simplicity. Gradients of red and grey can turn out pretty profitable also.
4. Black – white – gold
This is another killer combination. The simplicity of black combined with the richness of gold helps you create a cover that makes people turn their heads just to see it. Usually these colors are ideal for conservatory institutions that deal a lot with money.
3. Red – white – blue
You should take good care not to have red-blue bordering areas, or – if you do, one of the colors should be really dark while the other is lighten. Blue and white is another good combination that derives from this one. It is used more and more in the internet marketing – new technologies field because of the trustness the blue color implies.
2. Red – orange – green
Orange seems to be a color preferred by the customers. Psychologically speaking, orange gives a sense of affordability and combined with red, which is a strong motivator, subconsciously influence your leads to act. The green color brings in a little freshness into the picture so it fits well for ecological and sport projects.
1. Red – orange – blue
Based on numerous split tests and feedback from my customers, the absolute combination was formed from red, orange and blue – or, to be more specific: dark blue. 
The blue color adds the touch of confidence – needed by each of us before we make the buying decision – to the red-orange combination.
