Colouring a word guess goes wrong when a letter appears twice

Mark each letter right, misplaced or absent and it works until a guess repeats a letter the secret has only once, and then players are told something false. This entry shows the order of marking that keeps every colour honest and how the on-screen keyboard should remember them.

Why this works

Each letter of the secret can vouch for only one letter of the guess. So the exact matches claim their letters first, and only what is left over can be marked as misplaced, which is why the order of the two passes matters.

When not to use it

If your game shows only how many letters are right, or hides which position is which, the colours are not needed. And in a game where hints should be vague on purpose, giving exact feedback per letter makes the puzzle too easy.
