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:
Black Green Black Black Green Black
Green Black Green Green Black Green
Black Green Green Black Green Green

Output:
Black Gray Gray Black Gray Gray Black Gray Gray Black Gray Gray
Gray Black Gray Gray Black Gray Gray Black Gray Gray Black Gray
Black Gray Gray Black Gray Gray Black Gray Gray Black Gray Gray


Example 2
Input:
Black Green Black Black Green Black
Green Green Green Green Green Green
Black Black Green Black Black Green

Output:
Black Gray Black Black Gray Black Black Gray Black Black Gray Black
Gray Gray Gray Gray Gray Gray Gray Gray Gray Gray Gray Gray
Black Black Gray Black Black Gray Black Black Gray Black Black Gray


Example 3
Input:
Black Black Green Black Black Black
Black Green Green Green Black Green
Green Black Green Black Green Black

Output:
Gray Black Gray Black Gray Black Gray Black Gray Black Gray Black
Black Gray Gray Gray Black Gray Gray Gray Black Gray Gray Gray
Gray Black Gray Black Gray Black Gray Black Gray Black Gray Black


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


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