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 Blue Blue Blue Black Black Orange Orange
Black Black Blue Blue Black Black Orange Black
Black Blue Blue Blue Black Orange Orange Black
Black Black Black Black Black Black Black Black
Black Black Black Brown Black Black Black Black
Black Black Brown Brown Brown Black Black Black
Black Black Black Brown Black Black Black Black
Black Black Black Black Black Black Black Black

Output:
Blue Black Black
Black Orange Black
