A sketch of my paint box. I’ve replaced one of the blues with cerulean blue, because I missed it and the previous light blue just didn’t make the right hue I wanted. I also miss paynes grey for shadows. I’m sure I could mix up decent shadow colours, but the point of on-the-spot sketching is it’s fast, and for that paynes grey works just fine – as well as being a good quick grey in black and white sketches.

I did this sketch to test out the colours I have, and see if there are any obvious choices to swap out. At first I thought it was a toss up between the light green or mid brown, but once I did this sketch I could see that three shades of blue is more than I need.

Trouble is, I have been trying to get a hold of paynes grey, but every time I’ve been near an art store they’ve either been out of stock or closed.
