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 Black Black Black Black
Black Black Black Black Black
Gray Black Black Black Blue
Black Black Orange Black Yellow
Black Black Black Black Black
Black Pink Black Red Black

Output:
Green


Example 2
