If I run out of colour (black) while airbrushing can I substitute/mix regular colour to complete the cake? I do not have time to get into the city for extra.

TIA

Yes you should be able to, just make sure you dilute it very well and that there are no lumps....well dissolved. Good luck!

thanks so much kitagrl, one more ? dilute with water, alcohol or does it matter.

With alcohol so that it dries faster...clear vanilla or vodka.

Good luck! There's actually a recent thread on this from last night...someone else ran into the same problem...I don't know where it is now though...
