Two attempts, on the left red printed on top of yellow and on the right yellow printed on top of red. The second one gives a slight idea of an orange colour, but I probably should try some extender. In which case should I add it to the top colour only or both?
This looks great. I have not had a chance to do anymore and Realise looking at this I have probably forgotten everything Tricia showed us already!
Lovely, I like both, but can see how you would get a better colour with the righthand one. You really only need to add extender to the top layer. Extender will also make your colours paler, so be careful how much you mix in and to which layer.
