Fuzz, I think. If I remember my 'scientific' experiment, it was mostly fuzz and dried leaf crumbles. It doesn't retain it's color, but might have if I had hung it upside down to dry. I kept mine in water till the blooms turned brown, I think. If you want to dry a flower, I don't think it needs to stay in water.
I'm really not an expert on dried flowers though, I'm the one who left roses on the dash of my car in the hot July sun so they'd dry really fast. They did.
