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 Black Black Black Black Black Black
Black Black Black Black Brown Gray Black Black
Black Black Black Brown Brown Gray Black Black
Black Black Brown Brown Brown Brown Black Black
Black Black Gray Gray Brown Purple Black Black
Black Black Black Black Black Black Black Black
Black Black Black Black Black Black Black Black

Output:
Black Black Brown Gray
Black Brown Brown Gray
Brown Brown Brown Brown
Gray Gray Brown Purple
