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 Black Black Black
Black Black Green Black Black Black Purple Black
Black Blue Green Black Black Brown Brown Black
Black Black Black Black Black Black Black Black
Black Black Black Blue Blue Black Black Black
Black Black Black Blue Blue Black Black Black

Output:
Black Green Black Black
Blue Green Black Black
Blue Blue Black Purple
Blue Blue Brown Brown
