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:
Brown Brown Black Brown
Black Purple Purple Brown
Brown Brown Purple Black
Brown Pink Pink Brown

Output:
Red Red Red Red
Red Red Red Red
Red Red Red Red
Red Red Red Red


Example 2
Input:
Black Black Red Gray
Black Black Gray Red
Red Gray Black Black
Gray Red Black Black

Output:
Red Red Red Red
Red Red Red Red
Red Red Red Red
Red Red Red Red


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

Output:
Red Red Red Red
Red Red Red Red
Red Red Red Red
Red Red Red Red


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


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