Second Sight
What is Second Sight?
Second Sight is a daily colour perception test that asks you to remember one colour and then identify how a second colour changed. The change can be in lightness, saturation, or hue. It is free to play in a browser and takes about 3–5 minutes per day.

A tidy little three-minute brain stretch that slots neatly into a coffee break.

Memory-based colour judgement with honest single-dimension feedback—but the growing pause demands real discipline.

It's like a perfect two-note hook for your eyes—you hum the first colour, then hear where it bends.

Daily rounds, streaks and a stat-tracking profile make chasing that perfect 10-run a proper completionist's hunt.
How to play Second Sight
You are shown a first colour, then a short pause, then a second colour. After the second colour, choose whether it became lighter, darker, more vivid, more muted, redder, greener, yellower, or bluer. The two colours appear together only after you commit to an answer.
Tips & strategy
- Try to describe the first colour in words: bright or dark, intense or greyish, and roughly which hue it has.
- The game itself advises trusting your first impression rather than overthinking the change.
- Expect the pause to feel longer later in the daily set, so hold the first colour in mind through the blank interval.
- Use the post-answer explanation: each round changes only one perceptual dimension, which can help you calibrate your next judgement.
- Remember that 'vivid' means more intense and 'muted' means closer to grey.
Frequently asked questions
Is Second Sight free?
Yes, it is free to play in a browser and requires no download.
How often is there a new puzzle?
A new set of ten colour comparisons is available daily.
Is this a medical vision test?
No, it is a perceptual memory game rather than a diagnostic assessment. Ambient light, display settings, and individual screens can affect how colours appear.
What do 'vivid' and 'muted' mean here?
Vivid means more intense; muted means closer to grey.
Do I ever see the two colours side by side?
Not before answering. The first colour disappears before the second appears, and the two are shown together only after you have made your choice.
