Normal colour vision is a required medical standard for Merchant Navy candidates. Read the hidden number on each plate to screen your colour perception in under a minute.
How it works

One clock runs for the whole test — 5 seconds for every plate drawn.
Answers are final
Once you tap an option it is locked in — choose carefully.
Timeout means no answer
If the clock runs out, the remaining plates are marked as no response.
