Your monitor is not calibrated.

Photoshop has a simple program to help you do this, but if you are attempting to calibrate for professional use, you will have to spend a couple of hundred dollars and buy a monitor calibration tool

Eye One is the one I use.

the rgb/ index setting is one option, file format is another jpg. png/ gif , and also channels,

and so if you're editing a gif with cymk mode and channels are not select, this would cause such an effect,

..
wow - it sounds like a couple issues

1. Really, really bad color calibration (which is a very slim possibility). Under the control panel, rerun your Adobe Gamma. This will correct your monitor colors to correct values.

2. What you see is not what you get. Just seeing a whole range of colors in the swatches, isn't enough. Check on the toolbar to make sure that your color is selected properly. Try resetting the colors to basic B%26W (press the D key). Then select the color you want from the swatch. There is the possibility that you were changing the background color and not the foreground color. So when you painted, you were using the foreground color, and not the color you selected. Make sure that you aren't pressing ALT when you select the color from the swatch pallette
Click on the color swatch and it will take you to the color spectrum, where you can pick out your brush color.
In the toolbar, go to Image, then mode, and change it to RGB.
Do you have some type of filter on?
It sounds like you may have your color mode set to monotone. Or, in the channels palette you managed to turn of the cyan, magenta and black palettes.
When you click on new document on the box that says what size and color the background will be there is a drop down menu! In that drop down menu choose RGB while working on the computer and before you print change it to CMYK. It will more then likely say gray scale or something!

Good Luck!
