How Can I Remove Dye Transfer on Silk Pants?

I have done a stupid thing and hand washed 100% silk pants that are dry clean only. They are red with white flowers on them. The red dye has bled into the white. I know I can't use Rit on them, being silk.

Is there any way I can do a spot-clean style stain removal on the white flower part? I'm really stuck, and want to fix it. Any advice would be awesome.
