The 100 hue test.
Put 85 colors in order, from one fixed cap to the next. A screen game after the classic Farnsworth-Munsell 100 hue test of 1943.
About the test.
Is this the Farnsworth-Munsell 100 hue test?
It follows its method: 85 caps in four trays, a fixed cap at each end of every tray, and the same scoring. The colors are drawn by your screen, so this is a game and a good warm-up, not the calibrated physical test.
What is the difference between the easy and the official version?
Both use the same 85 caps and the same score. The official version follows the original procedure: a black case, caps taken from the box one by one, the score at the end. The easy version starts with the caps shuffled in the row on a light tray; you drag them into order, and each tray is checked as you go, with the caps to move ringed in red.
How is the score computed?
Each cap scores the difference between its number and the numbers of its two neighbors; a cap in its place scores 2. The total error score adds every cap's score minus 2, so zero means a perfect order.
What is a good score?
On the original test, 16 or less is superior color discrimination, 20 to 100 is average and above 100 is low. On a screen, take these bands as a rough guide.
How were the colors chosen?
85 hues on a circle of constant lightness and chroma, spaced so that neighbors are about 1.8 apart in CIEDE2000, all inside the sRGB range of a standard screen.
Why is this test on the ColorLoop site?
Eyes differ from one person to the next, they tire over a shift, and the light in a pressroom changes. That is why printers measure color. ColorLoop presets the ink keys on sheetfed offset, then corrects after each measured sheet.
