This year's Easter eggs

I think I am making progress. Last year's eggs were all greenish blue and blueish black.
They still have to be painted, this will happen Friday morning, but so far so good.

Here is this years batch, pre-painting:

You cannot get white eggs in South Africa so you have to start with fairly dark brown eggs. So some of them in fact barely looked dyed at all even though I put more dye, more vinegar (that seemed to really make a difference) and let them boil a lot longer than ordered by instructions on the package.
I am half thinking of getting back to the shop getting more dyes and more eggs and starting over, trying for darker, brighter colours.
