Sonic Crackers - The Knuckles & Vector Pallete

These are the two palletes used for Sonic and Tails' sprites. The top row is for their bodies, heads and legs, and the bottom row is for their arms and link rings. What's interesting about the bottom pallete is the various shades of red and green. It's possible that these colours would be used for Knuckles and Vector.

Here are Knuckles & Vector from Chaotix.
