Dyeing bottle brush trees

I'm in a 'use what you have' kind of mood lately and been wanting to dye some of the bottlebrush trees that I have on hand. The directions are to remove the original green color by soaking them in a solution of bleach and water. I used various strengths and as you can imagine came out with different shades of green down to a creamish color. Further directions said to used dye to recolor. With only some food coloring on hand I decided to give that a try. The blues and blue greens did not turn out well at all. The green trees you see below are the result of watching and removing from the bleach solution at different times. A dozen of the pink were sent off a few weeks ago for a swap, they are my favorite. They all look much better in person. One thing I'd like to add is that different results were achieved with the different brands of trees. One batch literally melted. I never did achieve a nice clean white color so if you have, please let me know your secret. You can play with the shape of your trees by fluffing up or squishing down the bristles.

These are going to be fun to fix up and decorate.
