Very early lamps - did they come in anything except red/yellow/orange?

[Purity!]

I was just thinking that whenever i see any early crestworth stuff on ebay, or even hunters, the lava/liquid is always red/clear or red/yellow or some sort of orangey combination (hard to tell sometimes for the condition of them)

Tried having a look on flowoflava.com but the early sales brochure piccys are all in black and white.

So did the early lava lamps come in more interesting colours? Or just red/orange/yellows? Or was the red just the most popular?

I think the colours were probably more simple combinations then but then they got more experimantal and diverse.

Early liquid colors included rose, primrose (more purple than rose) yellow-green and blue-green. And maybe clear. Lava colors were emerald, ruby, topaz (yellow) and amber (orange). John, can you confirm please? John will know for certain.
