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:
Green Black Green Black Black Gray Black Black
Green Green Gray Green Black Black Black Green
Green Gray Blue Black Brown Black Black Brown
Black Green Black Purple Brown Black Black Gray
Gray Black Brown Black Gray Gray Black Black
Gray Green Brown Black Brown Black Gray Gray
Brown Black Green Black Brown Black Brown Purple
Purple Brown Blue Blue Black Black Brown Black
Black Green Black Black Purple Brown Green Green
Brown Green Purple Black Gray Green Brown Brown

Output:
Green
Gray
Blue
Brown
Purple
