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:
Gray Gray Gray Gray
Gray Gray Gray Gray
Gray Gray Gray Gray
Blue Gray Gray Gray

Output:
Gray Gray Gray Gray
Gray Gray Gray Gray
Gray Gray Gray Gray
Gray Blue Gray Gray


Example 2
Input:
Brown Brown Brown Yellow
Brown Brown Yellow Yellow
Brown Brown Brown Yellow
Brown Brown Yellow Brown

Output:
Brown Brown Yellow Brown

Yellow Orange Orange Yellow


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


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