Anybody here who has used the pygame module before should know about a colorkey. How do I set it?

PS. In case anybody didn't know, a colorkey is a RGB(A) value that when bound to a picture, replaces all pixels that are the color of the colorkey with another color, or transparent.

Any ideas?

Some thoughts running through my mind:
1. Maybe go pixel by pixel in a for loop. Use an if statement to determine if the pixel is that color. No clue how to do that.
2. Find a colorkey function. No clue how to do that.
3. Be open to suggestions. I know how to do that.

Why use color-keying when PNG files have a real alpha channel? It's a lot less work to convert your textures to PNG and add a proper alpha channel, if you ask me. In any case, PIL.Image.Image.putalpha may be what you're looking for. The docs aren't very clear about what exactly the band argument means though.

I have images in my clipboard I am using, plus the colorkey should be pretty easy. In pygame:

pygame.image.set_colorkey(0, 0, 0)
This takes any black on the image and converts it to clear.
