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

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


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

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


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

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:
Yellow Yellow Gray Brown
Yellow Red Gray Purple
Yellow Purple Black Gray
Yellow Gray Yellow Gray


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