hi, uhm without seeing it i would say use the magic wand tool , changing the tolerance as needed. This makes it easy for you to select parts of a picture. Next up to recolour there are loads of methods..for block colour you could just use the paint bucket tool :PaintBucketTool: , or for a bit of a better look you may want to use a gradiant tool . Or a even easier way is to use colour tint plugin (found in the plugin section of the forums), once selected your area just tint it the colour you want :wink:)
