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:
Brown Brown Brown Brown
Brown Gray Gray Brown
Brown Gray Gray Brown
Brown Brown Brown Brown

Output:
Blue Blue Blue Blue
Blue Blue Blue Blue
Blue Blue Blue Blue
Blue Blue Blue Blue


Example 2
Input:
Purple Black Black Purple
Purple Green Green Purple
Purple Black Black Purple
Orange Pink Pink Orange

Output:
Blue Blue Blue Blue
Blue Blue Blue Blue
Blue Blue Blue Blue
Blue Blue Blue Blue


Example 3
Input:
Pink Brown Blue Purple
Black Gray Blue Purple
Black Gray Blue Purple
Pink Brown Blue Purple

Output:
Blue Blue Blue Blue
Blue Blue Blue Blue
Blue Blue Blue Blue
Blue Blue Blue Blue


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


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