Can I ask for clarification of the colour issue on this thread with regard to the Rainbow range please? I'm wondering if, since this thread is from 2007, that knowledge or information on the colours may have changed in the intervening time.
But on here Bernard says
' Most examples are two-colour, a few three-colour. 'Nigel has said
'The colourways are: green and blue; green and pink; and blue and pink.' , which doesn't seem to indicate a three colour-way option.
And I have seen one id'd as Stevens and Williams with a horizontal optic ribbed barrel shaped body and with what appears to be 4 colours rainbow effect, pink,green,blue and purple.
I have also just bought a vase that I thought might be Stevens and Williams that may have a three colour rainbow effect and with bubbles, although since it hasn't arrived yet I can't tell whether or not it really might be Stevens and Williams, but I thought I'd start investigating anyway when I came upon this thread.
Any thoughts would be very helpful

Many thanks
