If you've been following my Instagram you'll know I've been exploring new colour combinations lately and blue/purple/magenta came up. I make a quick video of this little painting coming together in my sketchbook.
There are always learnings to be had from sketchbook time and this one was about Cobalt Blue. It's a super strength prismatic primary colour and very rich, I didn't love it on it's own but with the edges of it knocked off with other colours it felt less dominant.
My usual blue go-to is Phthalo Blue which is cooler which mixes so well with other colours and is less robust than the cobalt in terms of transparency.
I did find some printed papers that, with a nudge of glaze here and there, found their way into this one!
