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

Output:
Gray Brown Blue
Brown Brown Brown
Green Brown Red


Example 2
Input:
Gray Black Black Black Red
Black Black Black Black Black
Black Black Gray Black Black
Black Black Black Black Black
Purple Black Black Black Blue

Output:
Gray Brown Red
Brown Brown Brown
Purple Brown Blue


Example 3
Input:
Pink Black Black Black Red
Black Black Black Black Black
Black Black Gray Black Black
Black Black Black Black Black
Brown Black Black Black Purple

Output:
Pink Brown Red

Brown Brown Purple


Here is the input grid for the test example:
Input:
Yellow Black Black Black Green
Black Black Black Black Black
Black Black Gray Black Black
Black Black Black Black Black
Blue Black Black Black Red


Directly provide the output grids corresponding to the given test input grids, based on the patterns observed in the reference examples.
