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

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


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

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


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

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


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


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