But how do you find the color that is assigned to a single 8x8 tile?

For example, Zelda has the bomb displayed on the HUD as the color blue, but I want to change it to green. And green is a part of the palette set.

What's the best way to go about doing that, without actually changing the color blue. I want to select the green that is in the palette set.

The NES is kind of funky as far as palettes go. Instead of every 8x8 tile having a palette selected, palettes are selected for squares of 16x16, probably to save RAM.

This has the details.

Last view: 806 days 		The attribute table did the trick, because that blue bomb is actualy a bg tile, not a sprite tile. The sprite 0 bomb appears behind that blue BG tile when you initiate a scroll. Watch $200-$203 when you first initiate a scroll. Its palette is at $202.
