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

Output:
Black Purple Purple Purple Black
Black Black Black Purple Black
Purple Purple Black Purple Purple
