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:
Gray Blue Green
Red Brown Pink
Orange Purple Yellow

Output:
Black Black Black Black Black
Black Gray Blue Green Black
Black Red Brown Pink Black
Black Orange Purple Yellow Black
Black Black Black Black Black


Example 2
Input:
Yellow Orange
Green Blue

Output:
Black Black Black Black
Black Yellow Orange Black
Black Green Blue Black
Black Black Black Black


Example 3
Input:
Yellow Brown Gray
Red Pink Purple
Green Blue Orange

Output:
Black Black Black Black Black
Black Yellow Brown Gray Black
Black Red Pink Purple Black
Black Green Blue Orange Black
Black Black Black Black Black


Here is the input grid for the test example:
Input:
Orange Gray
Blue Purple


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