Buy a flash meant for your camera and get gels for it. Or, buy filters for your lens. Even better, edit the colour of the pictures on the computer; that's the beauty of digital.

Don't mess around using flashes not meant for your camera, at best it won't work correctly and at worst it will damage your camera.
