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 Black Pink Black
Black Black Black Black Black
Black Black Pink Orange Yellow
Yellow Black Purple Black Black
Black Black Gray Black Black

Output:
Red


Example 2
Input:
Pink Black Black Black Black
Purple Black Blue Black Red
Black Blue Green Gray Orange
Black Black Black Black Brown
Red Black Black Yellow Black

Output:
Red


Example 3
Input:
Black Blue Pink Orange Black
Orange Black Orange Green Black
Gray Black Black Yellow Gray
Black Blue Black Black Black
Yellow Black Black Black Pink

Output:
Red


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


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