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:
Pink
Orange
Purple
Yellow

Output:
Pink Pink
Orange Orange
Purple Purple
Yellow Yellow


Example 2
Input:
Red
Blue
Yellow
Orange

Yellow Yellow
Orange Orange
Pink Pink


Example 3
Input:
Yellow
Yellow
Brown
Gray
Orange

Output:
Yellow Yellow
Yellow Yellow
Brown Brown
Gray Gray
Orange Orange


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


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