When choosing colours, I look up to artists that inspire me. If I think the colours are nicely combined, i take the colour palette and play with that. Doing this, leads me to some amazing colour combinations, that I would never have imagined could contrast so nicely!
Here is an example of how I research colour combinations, from a De Kooning painting
and how it could be applied "inspire" interior design and graphics.
I hope you find this interesting and inspiring.
