Jenny Drake wrote an illustrated tutorial on Changing sky colour with the Gimp.
She does a great job of explaining her technique but I think she had a tough job as the sky was really washed out, – compositing two images, one for the landscape, one for the sky would have resulted in a better image maybe!
Still, something to try later..
how would you show sky colour in a science project
