I don't know, the one time I needed burgundy I put quite a lot of gel and my flowers had an almost true color. Then I glazed them when they were dry and got a deeper color. I'm guessing you don't have an airbrush? Can you find someone with an airbrush? What about petal dusts? Long shot here, but how about if you mix it with a bit of black? Can you change the color scheme?
