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 Brown Brown Brown Black Black
Black Black Black Black Brown Black Brown Black Black

Black Black Black Gray Black Black Brown Brown Black
Black Black Gray Gray Black Black Black Brown Black
Black Brown Brown Brown Black Black Black Brown Black
Black Brown Brown Brown Brown Brown Brown Brown Black
