help making a red chair turn white

OK I have a picture of a red velour colored recliner type chair that i want to make white instead of red. I've been messing with the hue/saturation but cant really get it. The thing is that there are parts of the picture where the velvet texture is naturally darker than the rest of the spots, and to keep the chair looking real and 3d, they have to stay a darker color than the white color I want to make it. but when i use the hue options, it just lightens everything on the chair. Here's the picture.

Layer it and hit ctrl-u...then adjust color accordingly...remember to click colorize.

Try using Desaturate, then tuning the result in Variations, selecting the different areas (Shadow, Midtones, Highlights) to regain the depth.
