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:
Green Blue Gray
Black Black Pink

Output:
Gray Gray Gray
Gray Gray Gray
Blue Blue Blue
Blue Blue Blue
Green Green Green
Green Green Green


Example 2
Input:
Brown Purple Red Gray
Black Black Black Green

Output:
Gray Gray Gray Gray
Gray Gray Gray Gray
Red Red Red Red
Red Red Red Red
Purple Purple Purple Purple
Purple Purple Purple Purple

Example 3
Input:
Purple Green Red Brown
Black Black Black Red

Output:
Brown Brown Brown Brown
Brown Brown Brown Brown
Red Red Red Red
Red Red Red Red
Green Green Green Green
Green Green Green Green
Purple Purple Purple Purple
Purple Purple Purple Purple


Here is the input grid for the test example:
Input:
Orange Yellow
Black Brown


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