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:
Green Blue Blue
Blue Red Black
Blue Black Black

Output:
Blue Blue Green
Black Red Blue

Example 2
Input:
Black Black Blue Purple
Black Black Blue Black

Black Orange Black


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