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 Yellow Black Yellow Black Black Yellow
Black Black Black Black Black Black Black Yellow Yellow Black Black

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

Output:
Yellow
