I've been working on my first mod, and I'm pretty sure all the coding is correct, but my Sprite seems to have inverted colors. Could someone help me out, and tell me if there's anything I've missed in terms of coding while I'm here anyways?
I also fully expect to be thrown into an incinerator for asking for help

As long as you use the search button and find nothing, you can expect only a mild scalding.
Your problem is palette, if I'm seeing it right. Did you open up a CC sprite and paste in yours?
Edit: This should work, but I didn't test it.

Ah, that fixed it. Thanks. I'll be sure to use the search function in the future.
