709 primaries share the same chromaticity values (and therefore the same gamut). 709 is the standard camera encoding color space for HDTV with a gamut identical to sRGB. So, I’m going to introduce you to the most common video color spaces you’ll hear about, and the one you’ll use for the web, mobile screens and broadcast television deliverables. While HDR is sexy and 4K HDR TV’s are in many homes around the world, reference grade HDR monitoring is out of reach for most of us. Your monitoring pipeline should be calibrated for the color space of the video standard that you will deliver in. How your video content will be consumed determines the video color space you need to create in and deliver. This could be a television, PC or laptop display, tablet, phone, cinema projector, or HDR television. All video is intended to be delivered and watched on some kind of display device. These values define how color information is encoded for a particular video standard.

A video color space defines RGB chromaticities that together determine a color gamut, a color component transfer function (often referred to using a confusing and unhelpful but common term “gamma”) and the chromaticity of a white point.
