# Setting color properties for a specific resolution

Choose the proper color property keys for the desired color range.

## Overview

Overview After specifying the AVVideoColorPropertiesKey, you must specify a color primary, transfer function, and Y’CbCr matrix. For HD colorimetry, specify: AVVideoColorPrimaries_ITU_R_709_2 AVVideoTransferFunction_ITU_R_709_2 AVVideoYCbCrMatrix_ITU_R_709_2 For SD colorimetry, specify: AVVideoColorPrimaries_SMPTE_C AVVideoTransferFunction_ITU_R_709_2 AVVideoYCbCrMatrix_ITU_R_601_4 For wide gamut HD colorimetry, specify: AVVideoColorPrimaries_P3_D65 AVVideoTransferFunction_ITU_R_709_2 AVVideoYCbCrMatrix_ITU_R_709_2 If the source and destination color properties differ, AVFoundation matches the color. You must tag the source.
