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

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


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

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


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

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


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


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