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:

Output:
Black Black Black Black Gray
Black Black Black Red Gray
Red Black Blue Gray Green
Black Blue Black Gray Green
Black Black Red Black Gray


Example 2
Input:
