Hey. Ive been following the same tutorials lately, and got the same results as you have at first. I managed to fix it, but cant remember exactly how i did it right now. Seems to me though, that 9 times out of 10, it was some sep rep fubar... ie 16 bit when it should have been 8 or vice versa.

The SNES uses indexed graphics. Typical (Mode 1) output would be 3 background planes and 1 sprite plane stacked on top of eachother. Background planes would display 32x28 tiles (NTSC) where each tile is 8x8 pixels. Each tile would use one palette out of a total of 8 and every palette consists of 15 colors + transparency.  There are 8 palettes for backgrounds and 8 for sprites. Background 1 and 2 are 4BPP and background 3 is 2BPP.  Bitdepth means that every pixel had 4 bits (or two) to assign a color, so 15 + transparency. 

There are other screen modes, zero to (the famous) 7,  but mode 1 was the most common afaik. 

This playlist is really cool if anyone wants to learn more :)
