When I had slikies I used to dye them many colours. Its not at all cruel. The birds could not care less. I used to bath them anyway for shows, and one day I decided to add some vegetable dye to the water. I had a red one too, and she was not pecked at. Maybe I was lucky. I had a red, blue, pink, green and a yellow one with a blue head. They looked very funny The pink one was my fav, she looked like candy floss.
