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 Pink Orange Brown Green Green Gray
Gray Brown Orange Gray Orange Blue Gray
Gray Purple Orange Yellow Purple Red Gray
Gray Gray Gray Gray Gray Gray Gray

Output:
Gray Gray Gray Gray Gray Gray Gray
Gray Red Purple Yellow Orange Purple Gray
Gray Blue Orange Gray Orange Brown Gray
Gray Green Green Brown Orange Pink Gray
Gray Gray Gray Gray Gray Gray Gray


Example 2
Input:
Gray Gray Gray Gray Gray
Gray Blue Gray Red Gray
Gray Blue Purple Brown Gray
Gray Brown Purple Purple Gray
