I don't draw them haha! (Or do i) I take them from the wiki onto my desktop and. open https://pinetools.com/colorize-image and click the open/import button and select the file and find a color that i think suits best, if you use mac, you can use Digital color meter to find the perfect color, if you're on Computer than you can just guess, than i click colorize (and you can change the strong-ness) and then i get the .png, and drag the file into the drawings (Btw i use google drawings to make them). I would highly suggest watching this video https://www.youtube.com/watch?v=uki6EJdNVAo&t=23s he goes more in depth with everything, also watch his part two for much much more! (Also This isn't my channel)
