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:
Brown Green Brown
Orange Green Orange
Green Black Green

Output:
Black Black Black

Here is the input grid for the test example:
Input:
Pink Orange Orange Pink
Black Pink Pink Black
Black Red Red Black


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