Whenever I'm trying to use the wand tool or the fill bucket it will proceed to go out of boundaries of what I am wanting selected. For instance, say you put in a filled red square and blue one next to each other on the same layer, then tried using the wand to only grab the red square or using the bucket to only fill in the red square a different color, it ends up effecting both squares when you only wanted the red. So, how come the wand and bucket cannot only grab onto one color? Examples of what I mean are in my photos, the first two being the wand tool and fill tool in action and the last one is what I wanted to happen. As you can see the wand tool and fill tool are wanting to fill in the entire boot instead of only grabbing/filling the gray area I wanted.
