The brightness of the palette makes me think it were a palette from Super Mario Advance 2. That's no bad thing though. Looks pretty nice.

A sunset palette that works with FP's rocky FG and a Wario Land 4 BG.

A kind of early morning palette that works with a doomship FG and a Dino City(?) BG.

Another sunset palette, but a lot brighter. Works with Len13's new mountain FG, and Broozer's mountain BG.
EDIT: Here are a few vanilla palettes that I put together fairly quickly:

A darker ice palette, which could also work underwater.


A dark castle-like palette.

Don't really know what to call this. It can kind of be used in a starry setting, similar to a star hill or star haven level.
