• 28 Snow is a good white color for digital and web site photography because it is a pure white with limited shine to it. The most popular color.
• 44 Jet is popular back color for both digital and film photography as it is a pure black without any hint of blue.
• 04 Neutral Grey is 18% grey and as it name implies it's a very neutral color and compliments black and red especially well.
• 93 Arctic White has florescence (a bit of a brightness and shine) and is generally used more for film photography rather than for use with a digital camera.
• 11 Royal Blue and 54 Stinger are both chromakey colors for photography and video which make it easier to cut out and paste a different background. 11 Royal blue can also double as a regular backdrop for portraiture because of it's pleasing and complimentary color. 54 Stinger is an excellent chromakey choice but is not usually a good choice as background color if you're not doing chromakey.
