The colors are fixed. Two words are impostors.
Welcome to Dworle, the reverse word puzzle!
Here is what a solved puzzle looks like.
The cells are colored based on the letter's position relative to the target word.
P, L, A, N from PLANE is colored GREEN because the position of each letter matches the position from PLANT.
A and T from WATER is colored YELLOW because they exist from the target word but the position is wrong.
W, E, R, E is black because they do not exist in the target word.
Red herrings are words that does not fit to any slots above the target word because it would violate the colored cell rules.
When the game starts, all the words on the screen will be shuffled. But the colored cells will remain the same.
Since the words are shuffled, the colord cell's rules is no longer true. From the green letters P, A, I, N from PAINT, only A matches from water. A from plant does exist in water but L does not. T's are colored black even though they exist in WATER. The red herrings might still be true but based on the previous checks, water might not be the target word.
Your goal, given the shuffled words, is to identify the target word, re-arrange the rest of the words so that the colored rules will be true, and identify the red herrings!
You successfully found the sequence and isolated the impostors.
