So I have made plenty of charcoal and other basic stars. Now getting back into pyro and want to start making different coloured stars.
I have looked through the Stars Fomula Sticky but i was after some formulas for easy colours, Red, purple and blue (i know its not that easy!). Ideally i wanted vivid colours not washed out.

Anyone got any specific formulas they they swear by?

Barium is not especially hazardous. Of course it is toxic and you should use all the available personal protection. But with gloves, a respirator, and good habits there is no more a risk then using charcoal.

I work with the stuff just about everyday on a very large scale, you just have to be safe. Don't let it keep you from making good greens!

You're going to find it difficult to make good greens without barium nitrate or chlorate. Zinc really is more of a turquoise color too.

As far as blue, I have heard good things about Shimizu blue #70

Potassium Perchlorate 63.8
Parlon 13.8
Copper(II) Oxide, black 12.9
Red Gum 9.5
Dextrin 4

For red, take the emerald green formula given above and replace the Barium nitrate with strontium nitrate.

Purple I haven't had much work with.

Indeed, the Ruby Red that MMMMMM Pyro pasted is Emerald Green with Sr(NO3)2 instead of (Ba(NO3)2.
