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 Red Red Black Black
Black Red Red Black Black
Black Blue Black Blue Black
Red Red Blue Black Blue
Red Red Black Black Blue
Black Blue Black Blue Black

Output:
Blue


Example 2
Input:
Black Blue Blue Black Black Black
Black Black Blue Black Black Black
Red Red Blue Blue Blue Black
Red Red Blue Red Red Black
Blue Black Black Red Red Blue
Black Black Black Blue Black Black

Output:
Blue


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

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


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