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 Blue Green
Brown Brown Brown

Output:
Gray Gray Green
Blue Blue Brown


Example 2
Input:
Gray Red Purple Brown
Yellow Yellow Yellow Yellow

Output:
Gray Gray Purple Brown
Red Red Yellow Yellow


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

Output:
Brown Brown Green Purple
Red Red Yellow Yellow


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


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