Color accuracy depends on a number of things:


1. The capability of a monitor to render certain color values on screen. Laptop screens are usually 6 bit, so they are not as capable as 8 bit screens. Even 8 bit screens usually render a color gamut (color space) called sRGB, which is fairly limited. Your camera captures a lot more color than that color you will not see on screen. Monitors that render Adobe RGB's color space will be a lot more capable of faithfully reproducing the colors captured with your camera. These screens are very expensive.This is about color SPACE: aka how many shades of each color a monitor is able to reproduce on screen to better match the colors that are actually in the captured image you took. (Depending on your camera: some cameras capture sRGB, others capture AdobeRGB, some capture 8 bit, some 16 etc. I shoot raw so this whole story is bades in that).





2. Calibration. No matter how well a monitor, 6 or 8 bit, sRGB or Adobe RGB, can render color spaces, ACCURACY is a matter of calibrating your screen. Every serious photographer need some device like Color Monkey (I keep misspelling it because they named it differently) or Pantone Huey Pro etc. There is calibration in every price range. Software calibration based on your eyes/perception only won't work.





So: get the screen you can afford, and get something to calibrate it with. I used to work in Graphic Design and got a Huey Pro (which is fairly affordable yet entry level in terms of calibration) and even that makes a huge difference.





(3. If you want your images to be faithfully reproduced: you need to start working with color profiles of your printer or of your photo lab but that is a whole other chapter).
