When you mix red and blue, you get purple; for a lighter shade, you just need white, which the icing itself would probably supply.
you start with white icing....... then add purple icing a little at a time...... to make purple, you mix red and blue. more red than blue though. If you use too much blue, it turns black......... now, the lilac icing will turn darker the longer it sits so you want to make it, ice the cake, then serve it right away....... It will turn the prettiest shade of dark purple the longer it sits.....
If you mix really light blue and pastel purple you get lilac.
You can only do this with paint but add white with purple
Blue and red make purple. Add white and you have lilac.
Lilac.
You can get lilac two ways. One, you can mix red and blue to get violet and then lighten to the shade of lilac with white. You can also eliminate some of the mixing by purchasing a violet or purple paint and then working with it and the white.
Lilac is a very light purple slightly tinged with blue. Mix (in paint) a tiny bit of crimson, a tiny bit of cerulean blue and massive amounts of white. It should yield lilac. Adjust the proportions until the colour is correct.
black, of course
I would say Potassium is the closest chemical to a purple as it is a lilac/purplish colour.

The colors teal and purple make a blueish gray color.
