Just a quick little walk through.
My good friends Donut said she'd wanna have a tutorial about sunset colouring, so this is what I've come up with. I know this isn't magnificent but I thought it would be a nice little mini tutorial in a series of sky tutorials!
First off I always start off with a base colour of your lightest shade. I generally do a lighter yellow like a Y32, Y21, or in this case YR20. because both my other yellows were dry and they're one of the few colours I have no refills for.
Next step, I start layering in some pinker tones. In this case I did some quick colouring starting from the top, going about 3/4's of the way down with R12. I blended it out right away with YR20 again.
last 2 steps together: Repeat the last step with R12, only half way down this time, then take a violet shade this time BV31, and only got 1/4 of the way down.
Always blending with the original YR20.
Anyway, I hope that was useful or interesting or something. See you later!
