For a main? My honest favorite is Rolling In The Deep by LostMomentos. I feel like it’s got the perfect header and stuff. Personally, if you’re looking for a RPG main theme, I’d look at their stuff. LostMomentos knows their shit. But if you’re looking for something more for a character or something like that, I’d go for nialljhoren’s themes.

If you’re uncertain of whether or not it’d be a good theme to use, look in the indie rp tag. Click one of their URLs and check their theme out. That’s typically where I found my themes. I feel like this ‘one type of color theme’ is bullshit. It’s too contrasty and yucky. But that’s just my opinion. I feel like in order to attract your eye, you have to have something more original, rather than the typical themes that most RPGs have nowadays.
