Getting the accurate colour has been a great challenge many a time with digital photography. A common problem is an undesirable colour cast, such as a blue, red, or green haze over the image. This was difficult to deal with when using film and often required special films or filters to balance the colour with the light.
Digital photography has really changed this because of white balance settings. Now you can select an in-camera white balance setting so that your camera records correct colours when shooting under a variety of different lighting conditions, such as incandescent light, tungsten light, sunshine, or clouds. You find icons representing presets for each of these in the white balance setting area or your camera. Auto white balance (AWB) gives less consistent results (even when working with RAW files).
Besides letting you choose an appropriate white balance setting, many digital cameras have a custom white balance setting that can record very accurate colours. Each camera deals with this setting differently, so you need to check your manual, though custom white balance requires that you have a neutral white or grey card for the control. If your camera offers such a feature (and most do), it is worth learning about and using.
Sometimes you may intentionally go wrong technically to aesthetically improve the photograph. you can add a preset white balance setting to add an attractive colour tone to a photo. For example, using a cloudy white balance setting can add warmth to an otherwise cold or blue-toned scene.
Most digital image-processing software offer several colour - correction tools. However, many of them work best if you have a pure white or neutral grey tone in your image. If your subject requires absolutely accurate colour, consider placing a white or grey card in the same light as your subject for a reference shot, and then remove the card for your actual shots. This reference shot can be used get very accurate colour in your final photograph.
