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:
Yellow Black Yellow Black
Yellow Yellow Black Yellow
Black Black Yellow Black
Black Yellow Black Black

Output:
Green Black Green Black Green Black Green Black
