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:
Yellow Red Green Purple Orange
Black Black Purple Green Black
Blue Black Orange Red Purple
Black Black Black Pink Black
Brown Black Blue Black Blue

Black Red Orange


Here is the input grid for the test example:
Input:
Black Gray Black Purple
Black Black Green Black
