Dying colored eggs

We only have one hen who lays white eggs, so most of our available eggs are either brown or blue.  Can those eggs be dyed for Easter?

Turns out yes, yes they can, but there is one obvious rule:

Put the blue eggs into your blue and purple dyes, while putting the brown eggs into your red and orange dyes.  Works much better than trying to dye a brown egg purple.  That just turns out ugly, let me tell you.
