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 Black Black Black Black Black Black Black Black

Black Black Black Black Black Black Green Green Black Black
Black Black Black Black Green Green Green Green Black Black
Black Black Black Black Black Black Green Green Black Black
Black Black Black Black Black Black Black Black Black Black

Output:
Black Black Gray Black
Black Black Green Green
Green Green Green Green
Black Black Green Green
