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:
Brown Pink Yellow Pink Orange Purple

Output:
Brown Brown Pink Pink Yellow Yellow Pink Pink Orange Orange Purple Purple


Example 2
Input:
Red Blue Yellow Orange Pink

Output:
Red Red Blue Blue 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 Brown Pink Green Gray Pink Gray


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