Color management is important for consistent color across different devices and color spaces. Different devices use different color codes to represent colors, like RGB values. To ensure accurate colors, it is important to understand the color spaces like Adobe RGB, sRGB, and CMYK used by devices and manage colors properly using the right codes. Settings like screen resolution, color management, and display calibration help ensure colors display accurately on screens. Shooting photos in RAW format also helps manage colors better across devices than JPEG format.
