It's important to realize that the images are everywhere, not just where you want or expect them to be.
When finding the right angle for a shot...'Move your ass.'
There really isn't anything that you could call 'bad' color. It all has to do with the amount of color you use and in what context it appears.
You need minimum color for maximum effect.
If you want to make more interesting pictures, become a more interesting person.
If you don't have a camera, the best thing you can do is describe how great it looked.
