I wondered, has anyone ever received a baby/toddler/child with a skin tone from the rainbow slider when adopting?
A friend of mine told me she has, and showed me screencaps of her game. Two of the kids she had the parents adopt were regular skin tones, but the third was a rainboo. (I don't have pics anymore, since they were photobucket hosted.) One of the parent sims did have a light blue skin tone from the slider.
On my game, both parents have the rainbow skin tone, the female is a lilac colour, and the father is a yellowish green. I am curious to see what would happen if they adopted, if they too would have a rainboo or not. The household is technically full, so I can't test it. (The female is pregnant, and there are some other relatives still alive.)
