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:
Brown Pink Yellow Pink
Orange Pink Gray Purple
Orange Green Green Brown

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


Example 2
