system
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:
Black Blue Blue Yellow
Blue Yellow Brown Brown
Yellow Brown Yellow Yellow
Yellow Blue Brown Black

Output:
Blue Blue Blue Blue
Blue Yellow Blue Yellow

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


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