Cricket is played in white in its longest format and in color everywhere else, a split that looks arbitrary until you trace where the whites came from. They started as ordinary summer clothing and became a rule about conduct.
White began as sensible summer dress
Light-colored cloth reflects heat and stays cooler in open sun, which mattered when matches ran across whole afternoons with no shade for the fielding side.
Flannel and later cotton in undyed or bleached form was also cheap and easy to launder, and it showed grass stains in a way that signaled effort rather than negligence.
None of that was a uniform decision. Players simply wore what gentlemen wore for outdoor recreation, and the sport inherited the convention without choosing it.
The red ball made the choice stick
Once the ball settled on dark red leather, a pale background gave batters the best possible contrast, especially in low evening light near the end of a day's play.
Sightscreens are painted white for the same reason in reverse, and the whole visual system of the traditional game is organized around a dark object moving against pale surroundings.
That coupling explains why a change of clothing color could not be made alone. Colored kit required a different ball, which required different lighting and a different format.
Whites became a claim about respectability
By the time the sport was codified, clean white clothing carried a clear class signal: it implied someone else did the laundry and the wearer did not work in the dirt.
Clubs wrote dress into their rules, schools enforced it, and the appearance of a team became part of how a match was judged before a ball was bowled.
Anything that departed from it read as vulgar, which is why later commercial experiments in colored clothing were attacked in moral language rather than practical language.
Floodlights forced the split
Night cricket needs a ball visible under artificial light, and a white ball is unusable against white clothing, so colored kit arrived as a consequence of scheduling rather than fashion.
Once the short formats adopted color, they gained something unplanned: team identity visible at a glance, which television and merchandising both reward.
The long format kept whites and thereby kept a visual argument that it is the older, more serious version, a distinction now maintained deliberately.
Two uniforms, two audiences
A spectator can now identify the format from a still photograph, which is unusual among sports and useful for broadcasters selling two different products.
Players describe the change of clothing as a change of mindset, and coaches lean on that, treating the kit as a cue for tempo and risk.
What began as summer comfort now functions as branding, and the traditionalists defending whites are defending a convenience that outlived its original reason.
