Color is skewed for in-game custom objects

[IceKnight366]

I'm working on a big custom scenery project and as soon as I entered the testing phase in game, the colors are skewed.  Everything that is supposed to be green is black, and things that are supposed to be white are green.  I tried running the object as static, animated, 24-bit BMP color, 256 color... I can't figure out when the colors aren't coming out right.  Never had this problem before, but this is the first time I've tried to open a custom scenery in Open RCT2.  Anyone else have this problem / what they did to fix it?

EDIT: Fixed it.  Was saving as 256-bit instead of 24 or 16-bit.  I'm a little rusty!
