Krissy - my camera always lies!
The wax is a kind of dull yellow or even cream.....makes me think of perfumed soap or the wax of a honeycomb. The original colour of the Fluidiums was 'spunk white' - which is very much what this is actually.
But the combination of a reflector light in the lamp and my camera's auto-tuning turns the wax yellow or even orange.
And whether Millenniums had white wax is something I know not, I'm afraid.
