what is your advice for colour? Especially how to keep colours bright while still being pleasant to look at…
My go-to technique is, I don't use that many different colours in one piece. For example, this piece basically just uses pink/purple hues, green/yellow hues, and blue. It makes stuff feel cohesive!
I do like going more wild with coloured lineart, then all bets are off haha. But generally, I tend to keep within a limited amount of colours - And I tend to use my favourite colors the most haha :-)) I don't worry too much honestly, I just keep going and have fun with it..
Oh, and another thing that makes stuff feel balanced: values..! that's a whole topic in itself, look it up if u'd like - if im unsure, i snap a pic with my phone, and turn it grayscale, to check if everything looks alright haha
