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:
Blue Blue Blue
Black Black Blue
Black Black Blue

Output:
Black Black Blue
Black Black Blue
Blue Blue Blue


Example 2
Input:
Black Black Purple
Blue Blue Purple

Black Blue Black
Purple Purple Purple


Example 3
Input:
Black Purple Black
Black Red Black
Blue Blue Blue

Output:
Blue Black Black
Blue Red Purple
Blue Black Black


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


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