Header Image
If your avatar is a picture of your face, your header image is what you see when you close your eyes. It should say, “yeah, this is who I am.” Or at least what your blog’s about. If you don’t like the way the header image looks on your blog, you can play with the “sliding header” and “stretch header image” settings or turn it off altogether.
Avatar
Since your avatar is the most familiar part of your Tumblr appearance, we thought it’d be nice to include it on your blog. But if you don’t like it, that’s cool too. You can hide it from your blog settings and it’ll only be used on the Dashboard.

Background and accent colors
There are no wrong colors.
