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 Black Black
Black Purple Black Pink
Black Black Brown Pink
Black Black Black Black

Output:
Black Black Black Black
Black Purple Black Black
Black Black Brown Black
Black Pink Pink Brown


Example 2
Input:
Orange Blue Gray Green Gray
Gray Yellow Red Pink Black
Brown Green Yellow Red Red
Black Blue Blue Purple Blue
Gray Orange Gray Gray Black

Output:
Orange Gray Brown Black Gray
Blue Yellow Green Blue Orange
Gray Red Yellow Blue Gray
Green Pink Red Purple Gray
Gray Green Red Blue Purple


Example 3
Input:
Brown Black Black Black Yellow
Black Blue Black Black Black
Black Black Black Red Black
Black Black Black Black Black
Pink Green Purple Black Black

Output:

Black Blue Black Black Green
Black Black Blue Black Purple
Black Black Red Blue Black
Yellow Black Black Red Blue


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