On a trip
The favourite: everyone takes their colour from day one and shoots wherever they are, in no rush to finish the collage. Voting waits until you're all back together.
Spin the wheel, take a colour, and photograph it at your own pace: on your commute, a weekend away, a whole trip. When you're back together, you build the collages and vote.

ChromaHunt is a game for groups of friends and families, shared from a single phone, with no accounts, no servers and no connection. Each player spins a colour wheel and lands on one at random; from there, the mission is to find objects in that colour and photograph them to fill a collage.
What makes the game click isn't sitting down to play it in one go, it's taking your colour travelling. No timer runs: everyone collects their photos at their own pace as they come across them, in a market, on a beach, in a new city, with no obligation to finish the collage at any set moment. Voting and the podium wait until the group is back together.
Playing it in one sitting still works: it's the original form of the challenge and it's just as good for a lazy Sunday or a birthday party. With kids you lower the bar (easy difficulty, a 2×2 grid, one minute per turn); with a bigger crowd you push up to all fourteen colours.
The game rewards a trained eye: that gold detail on a doorway, the turquoise of an awning, the brown of an old door. Suddenly you're walking down the street noticing things you hadn't looked at in years.
Everything happens on the device itself. The photos never leave it unless you download or share them, and a game can sit paused for days without losing anything.
Players take turns spinning. Each colour's weight halves for every player who already has it, so the game spreads different colours around instead of piling them up. Nobody gets stuck without a turn.
With your colour assigned, no timer runs: you take photos as you come across things in that shade, today or a week from now. Each photo fills one collage slot, and you can crop it, rotate it or swap it later.
When the group is back together, the gallery gathers every collage and each player rates the others with a face, from rough to amazing. Out comes a podium with real height differences and the group photo of a challenge well hunted.

The same game plays very differently depending on when you pick it up. These are the ones that work best.

How the challenge started: an afternoon without leaving the living room, hunting each colour around the house. With kids, easy difficulty, a 2×2 grid and a one-minute turn keep it moving.
One round per guest on the full grid, passing the phone around, voting saved for the end. A house rule, like no repeating a room in two photos in a row, keeps it lively.
It clicks with just two people too: on a long trip, on a lazy Sunday, or as a gift for someone who likes to look. Each with their own colour and collage, and you show each other the result at the end.
Easy is six colours, the ones in any living room: red, blue, yellow, green, white and black. Medium goes up to ten and hard reaches fourteen, with turquoise, lime, and metallic gold and silver. And if you want your own rules, custom mode lets you tick exactly which colours land on the wheel, and even add your own with a colour picker.

It works with two people or ten in the same game, and needs no minimum age or prior experience; on your own it works as a personal challenge. A quick round on a 2×2 grid takes five to ten minutes; a full 3×3 collage, built across a trip, can last days. There's no cap on rounds: play as many as you like and you set the pace.
