For the past few days I have been having fun playing with Color scheme Designer 3. This is free easily used, web based colour schemer which I am sure readers will enjoy.
From the section icons on the left of the screen you have options to explore mono, complimentary, triad, tetrad, analogic and accented analogic colour schemes.
If your colour scheme is just too bright to bear select “adjust scheme” from the tabs along the bottom left of the screen.
Which means this scheme. Can become this scheme by changing the Saturation and brightness or your shadows and lights.
Or this scheme.
I think you will enjoy it. I know I was lost for a few hours with it.
