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:
Gray Gray Gray
Gray Black Gray
Black Gray Gray

Output:
Gray Gray Gray
Gray Black Gray
Gray Gray Black


Example 2
Input:
Pink Pink
Black Pink

Output:
Pink Pink
Pink Black


Example 3
Input:
Orange Orange Orange
Orange Orange Orange
Black Orange Orange

Output:
Orange Orange Orange
Orange Orange Orange
Orange Orange Black


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


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