YIQ is the color space used by the analog NTSC color TV system. I stands for in-phase, while Q stands for quadrature, referring to the components used in quadrature amplitude modulation. Other TV systems used different color spaces, such as YUV for PAL or YDbDr for SECAM. Later digital standards use the YCbCr color space.
Color management is necessary because different devices have different color capabilities and characteristics. For example, a monitor may display colors differently than a printer can reproduce them. Without color management, the same image may appear differently on different devices, leading to inconsistencies and inaccuracies.
Multi-primary color (MPC) display is a display that can reproduce a wider gamut of color than conventional displays. In addition to the standard RGB (Red Green and Blue) color subpixels, the technology utilizes additional colors, such as yellow , magenta and cyan , and thus increases the range of displayable colors that the human eye can see.
A colour cast is a tint of a particular colour, usually unwanted, that evenly affects a photographic image in whole or in part. [1] Certain types of light can cause film and digital cameras to render a colour cast. Illuminating a subject with light sources of different colour temperatures will usually

Color matching software, such as Apple's ColorSync Utility for MacOS, measures a monitor's color temperature and then adjusts its settings accordingly. This enables on-screen color to more closely match printed color. Common monitor color temperatures, along with matching standard illuminants in parentheses, are as follows: 5000 K (CIE D50)
Color calibration of a monitor using ColorHug2, an open source colorimeter, placed on the screen. For calibrating the monitor a colorimeter is attached flat to the display's surface, shielded from all ambient light. The calibration software sends a series of color signals to the display and compares the values that were actually sent against ...
