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:
Blue Black Brown Black Red Black Pink Black
Black Brown Black Red Black Pink Black Purple
Brown Black Red Black Pink Black Purple Black
Black Red Black Pink Black Purple Black Gray
Red Black Pink Black Purple Black Gray Black
Black Pink Black Purple Black Gray Black Green

Output:
Blue Blue Blue Blue Blue Blue Blue Blue


Example 2
Input:
Gray Black Red Black Brown Black
Black Red Black Brown Black Yellow
Red Black Brown Black Yellow Black
Black Brown Black Yellow Black Orange
Brown Black Yellow Black Orange Black
Black Yellow Black Orange Black Pink
Yellow Black Orange Black Pink Black

Output:

Example 3
Input:
Purple Black Pink Black Green Black Yellow
Black Pink Black Green Black Yellow Black
Pink Black Green Black Yellow Black Gray
Black Green Black Yellow Black Gray Black
Green Black Yellow Black Gray Black Brown
