Help using GIMP

[FilmFoo]

Probably a really simple thing but, when I try to use the rubber or delete something on GIMP it goes to an orange colour.

I used that orange colour yesterday on GIMP when making an image, but now everything im deleting goes to that colour.

Do you know how to stop this?

Thanks 🙂

You probably have your background color set to orange.
