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 Black Gray
Blue Black Gray
Green Black Gray

Output:
Gray Gray Black
Blue Blue Black
Green Green Black


Example 2
Input:
Gray Black Gray
Red Black Gray
Purple Black Gray
Brown Black Gray

Output:
Gray Gray Black
Red Red Black
Purple Purple Black
Brown Brown Black


Example 3
Input:
Brown Black Gray
Red Black Gray
Green Black Gray
Purple Black Gray

Output:
Brown Brown Black
Red Red Black
Green Green Black
Purple Purple Black


Here is the input grid for the test example:
Input:
Yellow Black Gray
Orange Black Gray


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