Can't paint with foreground color - help

So I have this file, an index color mode gif, a very small red square.
I want to change it to a blue. So I change the foreground color to
blue. But when I use either Fill, or the Paint Bucket, or the Paint
Brush, it will only color it black. When I switch the foreground to
white, it will paint with white, and then if I change it to the same
red that is still in the image, it will paint with that red, but any
other color simply turns black. I am on the layer not the channel, and
there is only one layer.
What am I doing wrong, how do I get color onto this image?
I've opened up another file, an Index gif, and it works fine. I can't
seem to find any differences with these files or settings, I just don't
get it.

That's because you are trying to edit the 256 colors indexed image, but
blue isn't one of those 256 colors. Change it to RGB first and you
should be able to edit as normal.
