Test to See How You Dey See Color

• Where your blue start: na the hue wey your answer change from "green" go "blue". Hue na the angle wey color get for color circle; we use OKLCH color space, where equal steps for hue dey look almost equally different. For our scale, green dey near 140° and blue dey near 250°.
• The three color samples: one color wey green small pass your boundary, the boundary color itself, and one wey blue small pass am. Your friend fit call the one for middle by the other name.
• Error score: how far the colors for your rows dey from their correct order. Each color score na the gap between am and the two colors beside am, minus 2, so row wey dey correct order well-well get score 0. Smaller score better.
• The ring: every color for the hue circle, each with its own color. Spike wey long pass mean say mix-up big for that hue; "most mix-ups" show the area wey get the most.

No correct or wrong answer dey for your boundary. But error score get: 0 mean say na perfect. None of them be medical result.

1. Blue or green? One color go show at a time, on neutral grey. Tap Green or Blue, or press ← and →. Choose the first thing wey come your mind.
2. Getting closer. Two lines of colors dey move at the same time, one start near the green side and the other near the blue side, 12 colors each. If you answer "green", that line move toward blue; if you answer "blue", e move toward green, and the steps dey get smaller every time you change your mind. Both lines meet near your boundary.
3. Put colors in order. After that, you go get 4 rows of 12 colors. Every row get one fixed color for both ends; drag the colors, or tap two to change their places, until the row change smoothly. No clock dey.

All 52 colors for part 2 go round the color circle once, with about 6.9° between each hue, and the same lightness and colorfulness, so na only hue dey change. Your boundary na the 50% point of a curve wey we fit to your answers. The error score follow the rule wey the 100-hue test use.

• Your screen. Screens dey show color, brightness and settings different. Night mode, blue-light filters, "true tone" and dim screen dey shift colors toward yellow. Even the maker of the clinic 100-hue test talk say online version no fit give final result, because monitors dey different [8]. Compare results on the same screen.
• The room. Bright light or colored light around you dey change how the screen look.
• Your language. The words wey you use for colors dey shape where you put the line. Languages wey get separate names for light and dark blue, or use one name for green and blue together, dey draw different boundaries [2][4][9].
• Age and tiredness. Arranging colors dey harder as age increase [5], and tired eyes dey make colors wey close harder to arrange.
• Color vision. People wey get red-green color deficiency usually find some rows much harder. If some parts of the test feel impossible, eye doctor or optometrist fit test your color vision well.

The test to see how you dey see color show where you personally put the line between green and blue, and how well you fit arrange colors wey look almost the same on this screen. Na game wey research tasks inspire. E no be test for color blindness, e no be medical test, and e no be the Farnsworth–Munsell test itself: you no fit compare the scores with clinic standards. We no get any connection with X-Rite or Munsell.

If you think say you fit get color blindness, optometrist or eye doctor fit test you with correct plates and lighting.
