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 Black Black Black Blue
Black Red Black Black Red
Red Black Gray Orange Black
Black Red Black Black Blue
Black Black Blue Orange Black

Output:
Gray Gray Gray

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


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