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:
Gray Gray Gray Gray Gray Gray Gray Gray
Gray Black Black Black Black Black Black Gray
Gray Black Yellow Yellow Yellow Yellow Black Gray
Gray Black Yellow Yellow Yellow Yellow Black Gray
Gray Black Yellow Yellow Yellow Yellow Black Gray
Gray Black Yellow Yellow Yellow Yellow Black Gray
Gray Black Black Black Black Black Black Gray
Gray Gray Gray Gray Gray Gray Gray Gray

Output:
Black Black Black Black Black
Black Gray Gray Black Black
Black Gray Yellow Black Black
Black Black Black Black Black
Black Black Black Black Black
