I like the "Sweet Tones" scheme because it covers all the colors of the 80's but its not quite pastel, maybe the saturation of those tones can be slightly upped?
Like the beige or light lavender can be the background and the pink, blue, green could be the text, link and headers?
Also, instead of Alf, what about a character like a Smurf or a popular character from the Saturday morning cartoon 80's line up?
Is there a boombox there?
ETA: these colors look 80's-ish
