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:
Brown Black Yellow Black Yellow
Black Black Yellow Black Black
Yellow Yellow Yellow Yellow Yellow
Black Black Yellow Black Black
Blue Black Yellow Black Purple

Output:
Brown Black Yellow Black Yellow
Black Brown Yellow Yellow Black
Yellow Yellow Yellow Yellow Yellow
Black Blue Yellow Purple Black
Blue Black Yellow Black Purple


Example 2
Input:
Green Black Green Black Orange
