I’m curious which colors you used here…I like to try out various monochromatic palettes and this is one of the only yellow ones I’ve seen! Really like it. I’ve only got a couple yellow copics so I’d like to figure out which colors I should put on my next shopping list. Trev Murphy 8 years ago . Hi Brad, I used Y000, Y11, Y15, Y17, Y38 and some warm greys.
