If you want a quick colour blind check, the fastest move is an online Ishihara test. It gives you a rough answer fast.

The catch is simple. A screen is not a proper diagnostic setup. Brightness, night mode, cheap displays and glare can all wreck the result.

Quick answer

Use the online test for a rough screen. If you miss several plates, get a proper eye test. If you want to double-check at home, a printed test book is better than guessing off a phone.

If you want a physical version instead of relying on a screen, this is the simplest next step. SmartKoala may earn from qualifying purchases.

What an Ishihara test actually checks

Ishihara plates are built to catch common red-green colour vision issues. You look at dot patterns and try to spot a number, path or shape hidden in the colours.

This is where most get caught. Passing one or two plates does not mean perfect colour vision. Missing one or two also does not prove you are colour blind.

Online test vs printed book

Online is faster. Printed is cleaner.

What to do next

Start with the SmartKoala Ishihara colour blind test. If the result looks shaky, try a printed book or book an optometrist.

Compare the total pattern, not one plate. That is the part that actually matters.
