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 Yellow Yellow Yellow Black Green
Black Black Yellow Yellow Yellow Black Black
Black Green Yellow Yellow Yellow Black Black
Green Green Green Black Black Black Green
Yellow Yellow Yellow Green Black Black Black
Yellow Yellow Yellow Black Black Green Green
Yellow Yellow Yellow Black Green Black Black

Output:
Yellow


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