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 Brown Brown
Gray Gray Green
Brown Brown Brown

Output:
Brown Green Brown
Brown Gray Brown
Brown Gray Brown


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

Output:
Pink Pink Pink
Pink Brown Pink
Red Blue Yellow


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

Output:
Pink Blue Purple
Blue Blue Yellow
Pink Blue Purple


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


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