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:
Blue Gray Blue Gray Blue Gray Blue
Gray Blue Gray Blue Gray Blue Gray
Blue Gray Blue Gray Blue Gray Blue
Gray Blue Gray Blue Gray Blue Gray
Blue Gray Blue Gray Blue Gray Blue

Output:
Blue Gray Gray Gray Blue Blue Blue
Blue Gray Gray Gray Blue Blue Blue
Gray Blue Blue Blue Gray Gray Gray
Gray Blue Blue Blue Gray Gray Gray
Blue Gray Gray Gray Blue Blue Blue


Example 2
Input:
Gray Pink Gray Pink Gray
Pink Gray Pink Gray Pink
