About Color Vision Dot Game
This is not a medical test. It is for entertainment and general information only. Screen and lighting affect results. See an eye care professional for a diagnosis.
A free game where you try to pick out numbers and shapes hidden in fields of colored dots. There is no account to create, and you can play as many times as you like.
How the plates are made
Every plate is drawn fresh in your browser from a seed number, using original digit and shape outlines written for this game and randomly placed dots. No plates, figures or palettes were copied or traced from any published color vision test. A random game gets a new seed each time. Today’s plates uses a seed taken from the date, and so it changes each day.
How the colors are chosen
The color pairs follow a simplified model from color science: colors that a person lacking one type of cone cell cannot tell apart fall roughly along straight lines on a color chart. The game places the figure’s dots and the background’s dots on either side of such a line. The values it uses are approximations.
What the game cannot do
Its limits are real, so we want them stated clearly:
- It assumes a standard screen, but real phones and monitors vary, and night modes and room light change what reaches your eye.
- The model is simplified, and most inherited color vision differences do not fit it exactly.
- There are only 14 plates. The cutoffs for each summary were chosen by hand, and there has been no clinical or user study.
- It cannot diagnose anything. If you have concerns about your eyes, please see an eye care professional.
