Recreate a country's flag from memory.
Ready when you are
You have seen the French tricolore a thousand times. But could you dial in its exact blue? Flags takes a flag you already recognise, flashes it for five seconds, then takes it away and asks you to rebuild every band colour from memory. It is the same memory test as the rest of the game, wrapped around the colours nations actually fly — and it runs as the home of our Color World Cup, where your scores fly for your country.
Each round shows a three-band flag — a vertical tricolour like France or Ireland, or a horizontal one like Germany or the Netherlands. The flag’s name is shown while it is on screen, so the round is a memory test, not a quiz: you know which flag it is, the question is whether you can reproduce its colours. After the five-second flash the flag disappears and three slider banks appear, one per band. Switch between bands, dial each colour, and submit when all three are in.
The trap is assuming flag colours are the pure primaries they look like at a glance. Most are not. France’s blue is darker and less saturated than a crayon blue; Germany’s gold is closer to a deep yellow than orange; the “red” band on many flags carries a touch of orange or crimson. Anchor on the band you remember most confidently, get it exactly right, then judge the other two relative to it. White and black bands are near-free points — nail the obvious ones first and spend your attention on the chromatic band.
Each band is scored separately with CIEDE2000, the perceptual colour-difference standard, then the three are averaged for the round. Ten points a round, five flags, fifty points possible. Two strong bands and one weak one still average to a respectable score, which makes Flags more forgiving than it looks — but a run of confident-yet-wrong band colours is punished hard. Post a score and it counts toward your country on the Color World Cup table.
