Given input-output grid pairs as reference examples, carefully observe the patterns to predict the output grid for new test input. Each pair follows the same transformation rule. Grids are 2D arrays represented as strings, with cells (colors) separated by spaces and rows by newlines.
Here are the input and output grids for the reference examples:
Example 1
Input:
Purple Purple Purple Purple
Black Black Black Purple
Purple Purple Purple Purple

Output:
Black Purple Purple Purple Purple
Purple Purple Purple Purple Purple
Black Black Black Black Purple
Purple Purple Purple Purple Purple


Example 2
Input:
Red Red Black Black
Red Red Red Red
Black Black Red Red
Black Black Red Red
Black Black Red Red
Black Black Black Red

Output:
Black Red Red Black Black
Red Red Red Black Black

Black Black Black Red Red
Black Black Black Red Red
Black Black Black Red Red
Black Black Black Black Red


Example 3
Input:
Black Black Black Black Brown
Black Brown Black Brown Brown
Green Green Brown Brown Black
Green Black Brown Black Black
Green Brown Black Black Black

Output:
