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
Blue Blue Blue Black

Green Green Green Green
Black Blue Blue Blue
Blue Blue Blue Black
Blue Blue Black Blue
Black Black Blue Black
Green Green Green Green
Yellow Yellow Black Black
Black Black Yellow Black
