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:
Black Black Black
Black Black Black
Black Black Black
Black Black Black
Blue Gray Green

Output:

Green Green Green


Example 2
Input:

Brown Pink Red

Output:
Brown Brown Brown
Pink Pink Pink
Red Red Red


Here is the input grid for the test example:
Input:
