You don't need a uniform color: We used a mixture of brick red, browns and grays, and then threw in seashells, branches and various types of rock, so our walls ended up looking like cave paintings!
The funny thing is most people don't approach me because they are scared, and that's fine, I want to keep it that way. But the thing is if you're not scared or get over it you learn that sometimes what you're scared of is really what you shouldn't be scared of.
