While it may be tempting to start off with the brightest or boldest paint colour, you'll want to start with the lightest colour as your base. This makes the rest of your colours come out more vibrant and makes it easier to blend throughout the process. Even if you're look features primarily darker colours, use some light colours to add depth. If you need an example: think about a clown makeup look. You'd start with a white base, then add a yellow or orange around the cheekbones, nose, and so on. Next, you'd add red as your defining colour, then add more depth with blacks and browns.
