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 Black Green Green
Black Black Black Black
Green Black Green Green
Green Black Green Green

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


Example 2
Input:
Blue Black Blue Blue
Black Black Black Black
Blue Black Blue Blue
Blue Black Blue Blue

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


Example 3
Input:
Red Black Red Red
Black Black Black Black
Red Black Red Red
Red Black Red Red

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


Here is the input grid for the test example:
Input:
Yellow Black Yellow Yellow
Black Black Black Black
Yellow Black Yellow Yellow
Yellow Black Yellow Yellow


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