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 Blue Black
Red Black Gray
Black Green Black

Output:
Black Gray Black
Green Green Blue
Black Red Black


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

Output:
Black Gray Black
Purple Purple Red
Black Blue Black


Example 3
Input:
Black Red Black
Purple Black Pink
Black Brown Black

Output:
Black Pink Black
Brown Brown Red
Black Purple Black


Here is the input grid for the test example:
Input:
Black Green Black
Red Black Yellow
Black Blue Black


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