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 Orange Pink Yellow Pink Brown Purple Gray

Output:
Purple Black Black Black Black Black Black Black


Example 2
Input:
Pink Orange Yellow Blue Red Green Pink

Output:
Pink Black Black Black Black Black Black


Example 3
Input:
Orange Gray Brown Yellow Yellow Red Green

Output:
Orange Black Black Black Black Black Black


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


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