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:
Blue Blue Yellow Yellow
Blue Blue Yellow Yellow
Green Green Red Red
Green Green Red Red

Output:
Yellow
Green
Blue
Red


Example 2
Input:
Green Green Red Red
Green Green Red Red
Blue Blue Yellow Yellow
Blue Blue Yellow Yellow

Output:
Yellow
Green
Blue
Red


Example 3
Input:
Green Green Red Red
Green Green Red Red
Yellow Yellow Blue Blue
Yellow Yellow Blue Blue

Output:
Yellow
Green
Blue
Red


Here is the input grid for the test example:
Input:
Red Red Blue Blue
Red Red Blue Blue
Yellow Yellow Green Green
Yellow Yellow Green Green


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