Correct colors are very important to get realistic and good photos. Digital cameras cannot really tell what is white and what is not and this varies on the light and light sources. If your camera or you do not adjust for this, the colors in your photos will be wrong both on screen and on prints.
To fix this problem, most cameras have a white balance setting in the camera for daylight, flashlight etc. Some also have automatic adjustments of white balance that works pretty well. However, the camera is still guessing as it does not have a proper reference. You can however get far better results using the right equipment.
The cheapest way is to take a picture of a greycard, which is 18 % grey. This will give an accurate reading of what is white in the picture. An even better way is to use a filter, f.ex. Expodisc that you put in front of your lens and shot a picture through.
Afterwards you can use your compute software to read the withebalance from your shot, and paste this whitebalance into every photograph taken under the same conditions. I use Expodisc and Lightroom to make these corrections. Then, if you have a calibrated screen on your computer, you will know what the correct colors should be and can make your adjustments with a correct reference. Also, if you use a calibrated printer with ICC profiling you will get the same, correct colors on your prints and you will have a good workflow.
