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 Black Blue Blue Blue Black
Gray Gray Gray Black Blue Blue Blue Black
Gray Gray Gray Black Blue Blue Blue Black
Black Black Black Black Black Black Black Black
Green Green Green Black Red Red Red Black
Green Green Green Black Red Red Red Black
Green Green Green Black Red Red Red Black
Black Black Black Black Black Black Black Black

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