I just found out you can do this with Adobe Photoshop:
1. Create a new document in RGB mode.
2. Use the airbrush to paint some simple black dots on
a white background.
3. Go to the mode menu and change it to Indexed Color.
4. Go to Color Table... under the mode menu and select a
color table (a palette) called Black Body. This is a
256 color palette with colors going from black-red-orange-
yellow to white.
5. Click OK.
6. Your dots should now look like hot, white-centered
fireballs with yellow-red outer edges on a black background.
I also have Paint Shop Pro, so I saved the bitmap and the palette
to a file and loaded them, and there was hardly any difference.
However, I think bitmap looked somewhat better in Photoshop.
To get it to work in PSP, you have to Decrease Color Depth to
256 colors (8-bit) and then goto Colors -> Load Palette
and make sure you have Maintain Indexes selected when loading
I don't know where this Black Body palette comes from (if you
can't find it in your directories), but if anybody wants it, I
could try to email it. It is a standard Microsoft PAL file, so
it should work in most graphic programs.
