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 Green Black Black
Black Black Black Green Black
Black Black Green Black Yellow
Black Black Black Black Black
Green Black Black Green Black
Yellow Black Black Black Black
Green Yellow Yellow Green Black

Output:
Black Black Yellow Black Black
Black Black Black Yellow Black
Black Black Yellow Black Green
Black Black Black Black Black
Yellow Black Black Yellow Black
Green Black Black Black Black
Yellow Green Green Yellow Black


Example 2
Input:
Yellow Green Black Black Black Black
Black Black Green Black Black Black
Green Black Black Black Black Yellow
Green Green Yellow Black Black Black
