Participant 1
Initial description: I followed the example of the First Output by coloring all of the squares in the 1st and 2nd row that weren't before, and the bottom two rows, leaving the middle two blank.
Final description: I thought the rule was to flip and color the opposite blocks with the light blue color.
Participant 2
Initial description: Alternating color's on the grid.
Final description: Alternating color's on the grid. (Black = Blue) but the different grid sizes threw me off.
Participant 3
Initial description: none
Final description: none
Participant 4
Initial description: Make output 6x4, then turn all squares black. Look at input and if a square is colored (not black) on the top and the bottom, then you put a light blue square in the corresponding square in the output.
Final description: Turn any squares blue on the output that are black on both the top and bottom of the input.
Participant 5
Initial description: Select a random color and place it on the grid accordingly to the correct output.

Participant 6
Initial description: I don't know

Participant 7
Initial description: Fill in the black squares on top two and bottom two lines with blue squares

Participant 8
Initial description: The rule was to replicate the same pattern of the top eight squares and the bottome eight squares of the input, replacing the darker color with the lighter color.
Final description: The rule was to replicate the top eight squares of the input exactly, with the light color corresponding to the dark color of the input. Also, the bottom left two squares were to be replicated in the same manner
Participant 9
Initial description: Change all the black to blue, and take all other colors out
Final description: I don't kow
