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

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


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

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


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

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


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


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