Participant 1

Initial description: I thought it would be to fill the inside of shapes with all red, trying to start back from 3 colors filled.

Final description: Fill in the top left square with red and leave the other shapes as they are, with only black inside the gray shapes.

Participant 3

Initial description: I believed the rule was that squares had to be filled it red, and squares with a shape in the remained black inside

Final description: The squares that need to be filled in with a color, are squares in which the black insides form a perfect square. If it's not a perfect square, aka a rectangle, leave it black inside. Squares with a shape inside of them always stay black inside.


Attempt 1: Incorrect
Attempt 2: Correct

Participant 4

Initial description: The ordering of the shapes and the amount of uncolored squares in the middle determines whether the uncolored squares are filled in.

Final description: Shapes that have the same width and height have the middle uncolored squares filled in with the red color. However, this doesn't apply to the second shape as the shape in the middle is unusual and those types are never filled in.
