# Image Buffer Color Primaries Constants

Constants that indicate the color primaries gamut for the image buffer.

## Overview

Overview Use the kCVImageBufferColorPrimariesKey key to attach one of these values to the image buffer. The color primaries gamut describes the rendering intent of an image, for use in color matching operations, along with a transfer function (See Image Buffer Transfer Function Constants for more information.).
