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.

The ICC profile for a printer is created by comparing a test print result using a photometer with the original reference file. The test chart contains known CMYK colors, whose offsets to their actual L*a*b* colors scanned by the photometer result in an ICC profile. Another possibility to ICC profile a printer is to use a calibrated scanner as ...
They allow for the possibility of color vision through the comparison of absorbance across different types of cones. [10] According to Marshall et al., most animals in the marine habitat possess no or relatively simple color vision. However, there is a greater diversity in color vision in the ocean than there is on land.
An Ishihara test image as seen by subjects with normal color vision and by those with a variety of color deficiencies. A pseudoisochromatic plate (from Greek pseudo, meaning "false", iso, meaning "same" and chromo, meaning "color"), often abbreviated as PIP, is a style of standard exemplified by the Ishihara test, generally used for screening of color vision defects.
The Ishihara test is a color vision test for detection of red–green color deficiencies. It was named after its designer, Shinobu Ishihara, a professor at the University of Tokyo, who first published his tests in 1917. [2] The test consists of a number of Ishihara plates, which are a type of pseudoisochromatic plate.
The test was developed by Dr. Dean Farnsworth (Commander, United States Navy) while stationed at the Naval Submarine Research Laboratory in New London, Connecticut during World War II. After its adoption by the United States Navy in 1954 as the standard color vision test for sailors aboard ship, it has additionally been used to screen flying ...
But City University test contains test plates that can be used to detect all types of color vision deficiencies. [4] The TCU test was derived from Farnsworth D15 color arrangement test. [ 2 ] The test consists of 10 plates, containing a central colored dot surrounded by four peripheral dots of different colors.
