The Farnsworth–Munsell 100 Hue Color Vision test is a color vision test often used to test for color blindness.The system was developed by Dean Farnsworth in the 1940s and it tests the ability to isolate and arrange minute differences in various color targets with constant value and chroma that cover all the visual hues described by the Munsell color system.

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 ...
Color analyzer: hardware that connects to a computer that measures the light and color produced by the display device. Test patterns: standard video test patterns that test the display’s ability to perform as expected. Video calibration software: software that receives the signals from the color analyzer and displays the data in numerical ...
The Atari ST series has a digital-to-analog converter of 3-bits, eight levels per RGB channel, featuring a 9-bit RGB palette (512 colors).Depending on the (proprietary) monitor type attached, it displays one of the 320×200, 16-colors and 640×200, 4-colors modes with the color monitor, or the high resolution 640×400 black and white mode with the monochrome monitor.
EBU 100/0/100/0 Colour Bars Displayed colours are only approximate due to different transfer and colour spaces used on web pages and video (BT.601 or BT.709). An alternate form of colour bars is the 100% Colour Bars or EBU 100/0/100/0 Colour Bars pattern (specified in ITU-R Rec. BT.1729 [8]), also known as the RGB pattern or full field bars, which consists of eight vertical bars of 100% ...
The test color is a single spectral color, for which the subject can adjust the brightness. The mixture color combines two spectral colors, for which the subject can adjust the proportion, thereby changing the hue. These two colored lights are positioned side-by-side and the subject changes the two parameters until the colors appear to match ...

Color targets such as the ColorChecker can be captured by cameras and other color input devices, and the resulting images’ output can be compared to the original chart, or to reference measurements, to test the degree to which image acquisition reproduction systems and processes approximate the human visual systems.
