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:
Purple Purple
Orange Orange
Black Green
Yellow Blue
Purple Yellow

Output:
Purple Purple
Orange Orange
Black Green
Blue Blue
Yellow Yellow


Example 2
Input:

Green Green
Yellow Yellow
Red Red


Example 3
Input:

Red Purple
Pink Green
Orange Black
Green Yellow

Output:
Blue Blue
Purple Purple
Green Green
Black Black
Yellow Yellow


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