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:
Yellow Black Gray
Black Brown Yellow
Black Brown Brown

Output:
Gray Yellow Yellow
Gray Black Black
Gray Black Black


Example 2
Input:
Black Purple Purple
Gray Gray Black
Black Yellow Gray

Output:
Yellow Purple Purple
Yellow Black Black
Yellow Black Black


Example 3
Input:
Gray Orange Black
Black Pink Orange
Pink Black Pink

Output:
Gray Orange Orange
Gray Black Black
Gray Black Black


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


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