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:
Purple Gray Purple Gray Purple
Purple Gray Purple Gray Purple
Gray Purple Purple Gray Purple
Purple Gray Purple Gray Purple

Output:
Gray Purple Gray Purple Gray
Gray Purple Gray Purple Gray
Purple Gray Gray Purple Gray
