From Tyler Hobbs, I found it really interesting that color/image mapping can be used to create a secondary palette for your generated artwork. I’ve used gradient maps before in my raster/illustrated work and I personally love them, so I look forward to attempting to do something similar with generative work. The example he showed was beautiful, and he made a great note of adjusting the secondary reference images colors to make them more stark and obvious when translated over the generative piece!
