5 camps · sound on for the best experience
Camp 01 · Sound → Colour
Hear a colour.
In chromesthesia, music and everyday noise arrive with colour — a trumpet may glow gold, a low note feel like deep violet. Play the keys and let the colours bloom.
Camp 02 · Letters → Colour
See a letter's colour.
Grapheme–colour synesthetes see letters and numbers tinted, with colours that stay the same for life. And no two people agree — compare three invented minds.
SYNESTHESIA 42
Switch between minds: same letters, different colours. For a real synesthete the mapping stays the same for life — meet a second mind to earn the badge.
Camp 03 · Words → Taste
Taste a word.
Lexical-gustatory synesthesia puts a flavour in the mouth when a word is heard, read or spoken. Names, days, places — everything can taste of something.
Hover or tap the words. Discover three to earn the badge (0/3). These are invented examples — every real taste-word map is personal.
Camp 04 · Time → Space
Walk through time.
Spatial-sequence synesthetes see months, numbers and weekdays laid out in space — often as a ring, a staircase or a winding path they can point to.
Where does time live?
For some synesthetes, months, weekdays and numbers have a fixed location — a ring around the body, a staircase, a landscape they can walk through. Tap a month to step into one invented map.
This is a made-up map. Yours — if you have one — is probably different, and has been the same since childhood.
Camp 05 · Crossed Wires
Feel your own wires cross.
You don't need synesthesia to experience automatic mixing of senses and meaning. A classic experiment shows how reading hijacks colour naming.
Name the ink colour of each word — ignore what it says. 12 rounds, as fast as you can.
Summit · 4,200 m
The view from up here.
Synesthesia affects an estimated 2–4% of people. It is not an illness: it is a different, stable, involuntary way of experiencing the world — and no two synesthetes see it the same way.
