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 Black Black Black Black Black Black
Black Black Black Blue Black Black Black Black
Black Black Blue Yellow Yellow Black Blue Blue
Blue Blue Blue Yellow Yellow Black Black Black
Black Black Blue Black Blue Black Black Blue
Black Black Yellow Yellow Blue Black Blue Black
Blue Black Yellow Yellow Black Black Black Black
Black Blue Black Black Blue Blue Blue Black

Output:
Yellow


Example 2
Input:
Black Black Black Black Black Blue Black Black Black
Yellow Yellow Black Black Blue Black Black Black Black
Yellow Yellow Black Blue Black Black Blue Black Black
Black Blue Blue Blue Blue Black Black Black Black
Black Blue Black Blue Yellow Yellow Black Blue Black
Black Blue Black Blue Yellow Yellow Black Black Black
Blue Black Blue Black Black Blue Black Black Black
Black Blue Black Black Black Black Black Black Black

Output:
Yellow


Example 3
Input:
Black Yellow Yellow Blue Black
Blue Yellow Yellow Black Black
Blue Black Black Black Black
