I'm trying to use GIMP to create a star chart for a fantasy world. Ideally close to what an imaginary observer might see if they walked outside and looked up at night on this world, but it's still a chart, rather than an attempt at a photorealistic image of the night sky (which is beyond my rather meagre abilities as an artist, anyway).

I tried simply making a black circular background and painting on white stars with the default circular brush in GIMP (different sizes for different magnitudes), but that looks rather boring. GIMP has a default brush called "Sparks", though, which has a pleasing yellow color to it and a star-looking shape that I'd like to use. Unfortunately, this brush ignores the foreground color, and always paints with that same shade of golden yellow, which isn't quite what I'm looking for. It also seems to have some built-in jitter - I can't make it paint just *one* star, it always puts a few down, as if I had turned on jitter. I would try editing the brush like in photoshop, but for one this brush in particular is read only ( I guess I can fix that by just coyping the brush file in the file system, but that seems cumbersome), and in any case none of the options seem to let me turn off what I need turned off anyway. What in GIMP controls whether a brush has its own color or uses the foreground color?

And of course, maybe I'm going about this the wrong way. If anyone has any other suggestions on how I might go about drawing semirealistic-looking stars on a black background, I'd love to hear them.
