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:
Yellow Red Black
Yellow Yellow Brown
Green Green Brown
Purple Blue Black

Output:
Yellow Yellow Red Red Black Black
Yellow Yellow Red Red Black Black
Yellow Yellow Yellow Yellow Brown Brown
Yellow Yellow Yellow Yellow Brown Brown
Green Green Green Green Brown Brown
Green Green Green Green Brown Brown
Purple Purple Blue Blue Black Black
Purple Purple Blue Blue Black Black


Example 2
Input:
