..yes I do know that green is not a primary colour, but it was the best word I could think of to describe the colour I am after - that being the green that gets used in otherwise primary-coloured toys, etc. I have a couple of cakes to do for very small boys and wanted to do a colourful combination of toys/balloons. The green paste I have is 'spruce green' and is too muddy to ever come up with a clean bright green.
What colour paste am I after, do you think - or is it easier to start with blue and yellow?
Possibly, yes - but also that (bottle green) may also be the shade of paste I am looking for.
BTW I have discovered the solution to green (or other colour) hands - a kitchenaid mixer with a dough hook - and I bought a 5kg box of white for the many cakes I have to do over the next six weeks, so I don't especially want to buy green if I can help it.
I think a trip to my (very friendly but not very local) sugracraft shop is called for.
