## About Color Blind Test

Modeled on the classic Ishihara color vision screening, this educational simulation walks you through twelve circular plates made of colored dots, each hiding a number woven into the pattern. The hidden digits are 12, 8, 6, 29, 5, 3, 15, 74, 7, 16, 42, and 2. For each plate you pick what you see from five answer buttons, and one option is always 'Nothing' for plates where you cannot make out a figure. The set includes one demo plate everyone should read, eight red-green tests, two blue-yellow (tritan) tests, and one difficult gray-discrimination plate.

There is no timer and no way to fail mid-test: the correct number is revealed after each answer and you always proceed through all twelve plates. At the end you get a results screen with percentage bars for Overall, Red-Green, and Blue-Yellow perception, plus a short summary. Both the start and results screens make clear this is an educational tool, not a medical diagnosis; a real color vision exam should be performed by an eye care professional.

## How to Play Color Blind Test

Each plate shows a circle filled with colored dots. Look for a number formed by dots of a different color and pick it from the five answer buttons, choosing 'Nothing' if you cannot see a figure. After you answer, the correct number is shown and the test moves on; wrong answers never end it. Work through all twelve plates, and the results screen breaks down your accuracy into Overall, Red-Green, and Blue-Yellow percentage bars.

## Controls

Click or tap one of the five answer buttons to record the number you see, or 'Nothing' if you see no figure. Keys 1-5 also select the answers, and ESC or P pauses.

## Color Blind Test Tips & Strategies

1. Give each plate a quick, relaxed glance rather than straining; the number usually appears at first look or not at all.
2. View the screen at a comfortable distance and in even lighting for the most accurate reading.
3. Don't agonize over a plate you can't read; choosing 'Nothing' is a valid and informative answer.
4. Note that some plates are meant to be hard, including the gray discrimination plate near the end.
5. Remember the summary is a screening simulation, so use it as a prompt to see a professional rather than a verdict.

## Frequently Asked Questions

### Does this game actually test for color blindness?

It is an educational simulation based on the Ishihara plate format, clearly labeled as such on the start and results screens. It can hint at red-green or blue-yellow weaknesses, but a real color vision exam should be performed by an eye care professional.

### How many plates are there and what do they test?

There are twelve plates: one demo plate, eight red-green tests, two blue-yellow (tritan) tests, and one difficult gray-discrimination plate. Each plate offers five answers, always including 'Nothing'.

### How are my results reported?

The results screen shows percentage bars for Overall, Red-Green, and Blue-Yellow accuracy. An overall score of 90 percent or higher reads as appearing normal, while under 70 percent in a category suggests a possible deficiency worth checking with a professional.
