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 Black Black Black Black
Black Black Black Black Black Black Black Black
Black Black Purple Black Black Gray Gray Black
Black Black Purple Purple Black Gray Gray Black
Black Black Black Black Black Black Black Black
Brown Brown Black Black Pink Pink Black Black
Brown Brown Black Black Pink Pink Black Black
Black Black Black Black Black Black Black Black

Output:
Gray
Pink
Brown

Input:
Yellow Yellow Black Black Black Black Black
Yellow Yellow Black Black Blue Blue Black
Black Black Black Black Blue Blue Black
Black Black Black Black Black Black Black
Black Black Black Black Black Black Black
