Look at art, life, nature, your figures,
your friends, family, pets, your car, your world in black and white once in a while. I know. Not with your eyes. Use photofilters to change something to black and white.
This will help you to see how you can achieve contrast in hues, can give you inspiration where to place and compositioning dark and bright colors to see harmony all over or bring attention to a certain spot. There is a reason why I did put my preview pictures on www.romanlappat.com in black/white. It teaches me if a figure and a paintjob I did works in terms of hues. Of course it is not all black and white, there is grey too ;)
Cheers and happy painting!
