Ok, that's color, now let's deal with gamma, and contrast.

Below are some boxes, one should be absolute black. Nothing on your monitor should be darker than the black box. Look at the black border around your monitor. It should be as black as that box. And nothing should be lighter than the white box. The gray boxes and the white box should have no tint to them. No pink or blue.




Gamma is next.

Step back from your monitor.
One of these numbered boxes is about the same shade as the surrounding.




That is your "screen gamma". Most photographer's web pages are designed for 1.8 Gamma. TV monitors are calibrated for 2.2 Gama.

How did you do ?
