What is color space?

The simplest explanation of color space is that it is the range of colors shown in a photo. There are two mail color spaces used in digital photography. Both have their advantages and disadvantages, depending on where and how an image is viewed.

The two main colr spaces are sRGB and AdobeRGB. An easier way to understand this is to think of color spaces as pallets of watercolors. AdobeRGB being one set with ten colors on it, and sRGB being another with five colors.
