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:
Green Yellow Yellow Black Black
Black Yellow Yellow Black Black
Black Green Black Green Black
Yellow Yellow Green Black Green
Yellow Yellow Black Black Green
Black Green Black Green Black

Output:
Green


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

Output:
Green


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

Output:
Green


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


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