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 Green Brown
Brown Gray Brown
Brown Gray Brown

Output:
Brown Brown Brown
Gray Gray Green
Brown Brown Brown


Example 2
Input:
Pink Pink Pink
Pink Brown Pink
Yellow Blue Red

Output:
Yellow Pink Pink
Blue Brown Pink
Red Pink Pink


Example 3
Input:
Purple Blue Pink
Yellow Blue Blue
Purple Blue Pink

Output:
Purple Yellow Purple
Blue Blue Blue
Pink Blue Pink


Here is the input grid for the test example:
Input:
Gray Purple Purple
Purple Brown Blue
Purple Blue Red


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