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:
Orange Purple Purple Black Black Black
Gray Green Brown Black Black Black
Red Green Brown Black Black Black
Yellow Yellow Yellow Black Black Black

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


Example 2
Input:
Gray Gray Black Black
Gray Gray Black Black
Yellow Gray Black Black

Yellow Gray Gray Yellow
Gray Gray Gray Gray
Gray Gray Gray Gray


Example 3
Input:
Blue Black Black
Blue Black Black
Yellow Black Black

Output:

Blue Blue Blue
Yellow Yellow Yellow


Here is the input grid for the test example:
Input:
Gray Gray Gray Black Black Black
Gray Pink Gray Black Black Black
Gray Pink Gray Black Black Black
Gray Gray Gray Black Black Black


Directly provide the output grids corresponding to the given test input grids, based on the patterns observed in the reference examples.
