Chamomile - getting ahead of myself

I am so looking forward to dyeing something that does not turn out to be brown, that I made a dye bath with some dried chamomile flowers. I'll be able to gather them fresh later on in the year. The results are shown below: from the left mordanted with alum, with copper, with alum+tin and finally alum + iron. The results are still a bit brown though. Well, fawn and khaki as well as a lovely clear yellow.
