Dyeing fabric

[sunshinenebula.livejournal.com]

Hello everyone! I had a question about dyeing fabric. I need the white parts in this fabric to be blue, so I was going to dye it. Will the dye also change the color of the brown, or will it be fairly unscathed?

And also, does anyone know where I could find a similar patterned fabric in blue and brown? Thought I'd throw it out there to see. :)

Thanks!

EDIT: Thanks for the help everyone!
