saving defaults?

[ratcreature]

Gimp used to start with the regular black foreground, white background color setting. At one point I must have done something without realizing, because now whenever I start the foreground color is set to a light pink. I want it to be black again, but I don't know how I get that reset. I tried picking black and then closing Gimp, but as soon as I start the program it switched back to the pink color. Where can I make it remember the default color selection?
