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

Output:
Yellow


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

Output:
Yellow


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