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 Black
Red Red Red Red Red Red
Green Green Black Black Green Green
Yellow Yellow Black Black Yellow Yellow
Yellow Yellow Black Black Yellow Yellow

Output:
Yellow Yellow Black Black Yellow Yellow
