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:
Red Black Red Black Black
Black Red Black Black Red
Black Red Black Black Black
Black Red Red Black Blue
Blue Black Red Blue Black

Output:
Red Black Black Black Blue
Black Blue Blue Blue Black
Blue Blue Black Black Blue
Red Black Black Black Black
Black Red Black Blue Black


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

Output:
Black Black Blue Black Black Black
