Hope you don't mind me asking, but how do you pick which colours to use for the lineart? Especially if you're using really dark colours?
All questions are welcomed! If I’m using pinkish/warm colors, the lineart is usually a dark velvet red. As for purple/blue/cool colors, I’ll probably use a dark violet or dark blue. Sometimes I add some gradient to make it prettier.
As for really dark colors though, like almost black, you might actually want to use light contrasting colors on your lineart if you think your lineart needs to be seen.
Ex. If you have some black jeans with a lot of detail and seams and don’t want the black lineart to fade into the black fabric, you can use any color lighter than black to make it contrast. Doesn’t have to be white. You can use a previously used color on the lineart for color harmony.
But if it’s not quite black, it’s okay to use darker lineart too. As long as it doesn’t completely fade in really, unless you want it to.
