Yes, I do custom painting. :)
I produce my own paint sometimes. Therefore I collect stones and sand from places I like and turn it into pigment later on.
(Basically by hitting it with a rock long enough until it gets powdery.)
It's a truly sensational feeling to paint with your own hand-crafted colours.
If you ever visit Bildrauschen Studio (You should! They're amazing) make sure to go to the bathroom. You'll find the end result of "Celine, can you please make our bathroom look better? Do whatever you want!"
