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

Output:
Green Green Green
Blue Blue Blue
Gray Gray Gray


Example 2
Input:
Brown
Purple
Red
Gray

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


Example 3
Input:
Purple
Green
Red
Brown

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


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


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