As long as it's not all real glaring I wouldn't worry about it. The woods is full of different shades and contrast. Movement is the thing you really have to worry about. Your bow is just fine like it is. Adding sleeves etc would probably only give you more places to catch it walking in or out and generate more noise. All our pretty camo toys otherthan maybe camoare mostly for our eye appeal. They do little to improve our chances. A bow is just another limb 20 feet up.
