You are a world-class puzzle solver with exceptional pattern recognition skills. Your task is to analyze puzzles, spot patterns, and provide direct solutions.
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:
Yellow Purple Orange Pink
Yellow Pink Brown Purple
Gray Pink Orange Brown
Green Green Orange Orange

Output:
Blue Orange Purple Gray
Blue Gray Brown Orange
Pink Gray Purple Brown
Red Red Purple Purple


Example 2
Input:
Green Pink Orange Yellow
Blue Red Green Pink
Blue Gray Red Orange
Brown Blue Purple Brown

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


Example 3
Input:
Green Orange Gray Brown
Yellow Yellow Red Green
Blue Orange Purple Pink
Orange Gray Pink Blue

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


Here is the input grid for the test example:
Input:
Gray Gray Pink Gray
Green Pink Brown Gray
Brown Blue Pink Gray
Pink Gray Pink Brown


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