I have a sprite which is includes a lot of black, so I can't use that as the transparent color, so I chose purple. But I can't find a command to change the transparent color (like the set colorkey command in dbpro). If there is no such command what am I supposed to do... decide I can't use a certain color for my sprite (insane)?

Set Image Colorkey is the command you looking for, but make sure you use it in the right place, it's best called before you load your sprite images.

Sounds like you're working with something like the tiles from Duke Nukem 3D,,, or an other build based game,,,
Anyway, I've run into the same problem.
What I did was to change the black color to an other color very near to black, and then change the purple to black.

This can be done using DB, by making the program search through the image, and then automaticly change the colors.

Images using purpel as the transparent color are mostly 256-color-based, which allows you to use my method with no loss of visual quality

indi: my sprite is rendered from a 3D model...
Manson: Interesting plan... maybe I'll try that if turning the lighting up doesn't work.
arctarus: It doesn't seem you realize I already have DBC, and I'm getting DBP as soon as possible.

I did change the render background (to purple), but my character is almost entirely black.

ok if u select the outside magenta with a wand or magic wand tool at a tolerance of zero and anti aliasing off

After u have clicked in the magenta u want to inverse the selection.

Once u have done this the whole 2d character is selected instead of the outside.

from here I would set brightness and record how much then use an eye dropper to check the black levels.

rgb 25,25,25 or rgb 35,35,35 for the black areas as an example in the sprite pixels.

once u have done this inverse the selection again and paint the background with rgb 0,0,0 and no anti aliasing

then save out.

if thats a bit daunting just say and ill post the bmp
