-- yeah, just, color me.
STEP 3 in meh process: I add color. I make sure that ink has dried. If you don't know what I'm talkin' about then look at the previous step.
I use watercolor paint. Nothing fancy. I've tried a few different types of watercolors: squirtey-tubey kinds, liquidey kinds, and dry kinds in the nifty trays. Frankly, I prefer the dried palette kinds. Not necessarily Crayola, but like, the mid-range Hobby Lobby brand that has 24 colors. It works great and gives me the look I want for Somewhat Adventures. I like the color palette of this set and it doesn't break the bank......always a nice bonus.
I use a couple of round tip. soft (for watercolor) brushes. Again, not the absolute cheapest and not the most expensive. I use coupons and watch for sales, too. The sizes I use.....medium-ish to small-ish. Really, you just need to find what's comfortable and affordable and just overall works for YOU.
For Somewhat Adventures, I try not to get too mix-ey with it, so I can stay consistent throughout the story, more easily. It's a good practice to mix colors, at least a bit, rather than just applying one, flat color to an area. I actually do mix lightly, on the page. Then I can achieve some depth and harmony, buuuuut not too much complication.
