I’ve seen this question come up A LOT lately! Maybe its from the warmer, sunnier weather 🙂 This little bit is something I learned when I used to do a lot more painting but the idea totally applies to copics too. If you try to shade yellow with a grey/black it usually turns out green and just kind of icky. I always encourage you to experiment and find your own likes but Y26 and Y28 are my go tos for shading yellow. I hope you enjoyed the tut and I hope it was helpful!
