Color?

How do you know, when viewing an image, if you are seeing the right colors on your monitor? We have 8 monitors in our studio and each of them can show the same image with totally different colors. Ack. So what do you do? How can you better ensure that you are seeing a web page or an image on your screen that is closer to what the author intended? There are hardware devices and even specialized monitors that can help in this area, but what can the regular user do to help better calibrate their monitor? If you have a monitor and video card that have the right adjustment features (gamma, brightness, contrast, color temperature and so on) you can calibrate your monitor to better represent colors on your screen.
