Court Colors

[1MCGRADY1]

Hey, which color do you use when you're changing logo files? For example, if I was to open the midcourt logo for the Hawks and switch it out with a retro Hawks logo, say, that I'm pasting in, what color would I put as the background? I tried black, and the logo was in a black square. I was thinking the grey color that shows up on Dolffin may work, but I haven't tried it yet. Well, I know I've seen perfect custom court logos for this game, so if anyone can help me out that would be great.
