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 Black Green
Black Black Blue
Black Black Gray

Output:
Green Green Green
Blue Blue Blue
Gray Gray Gray


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

Output:
Purple Purple Purple
Red Red Red
Gray Gray Gray


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

Output:
Brown Brown Brown
Red Red Red
Pink Pink Pink


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


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