Hue & Saturation
I made a very quick acrylic painting using RGB colours, I then made various edits of the painting on photoshop in different CMYK colours. Playing around with the hue and situration on photoshop was great, as it is a quick and easy way to to see how different colours work with or against each other.
I liked the one on the top left the most, I felt it was the least garish, and the colours were closest to ones that I would use in my own paintings.
