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:
Black Black Black Black Purple Green Green
Black Black Black Black Black Green Brown
Black Black Black Black Black Brown Brown
Black Black Black Black Black Brown Black

Output:
Green Green Purple Purple Green Green
Brown Green Black Black Green Brown
Brown Brown Black Black Brown Brown
Black Brown Black Black Brown Black


Example 2
