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:
Orange Green
Brown Gray

Output:
Orange Green
Black Gray


Example 2
Input:
Orange Red
Green Brown

Output:
Orange Red
Green Black


Example 3
Input:
Brown Brown
Gray Purple

Output:
Black Black
Gray Purple


Here is the input grid for the test example:
Input:
Green Pink
Brown Pink


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