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:
Purple Blue Brown Pink
Purple Blue Gray Black
Purple Blue Gray Black
Purple Blue Brown Pink

Output:
Pink Black Black Pink
Brown Gray Gray Brown
Blue Blue Blue Blue
Purple Purple Purple Purple


Example 2
Input:
Green Black Black Black Green
Brown Black Black Black Brown
Purple Purple Gray Purple Purple
Purple Purple Gray Purple Purple
Yellow Yellow Yellow Yellow Yellow
Yellow Yellow Black Yellow Yellow

Output:
Green Brown Purple Purple Yellow Yellow
Black Black Purple Purple Yellow Yellow
Black Black Gray Gray Yellow Black
Black Black Purple Purple Yellow Yellow
Green Brown Purple Purple Yellow Yellow


Example 3
Input:
Purple Yellow Blue Blue Black Black
Orange Yellow Green Brown Green Green
Gray Gray Green Green Green Black
Orange Yellow Green Brown Green Green
Purple Yellow Blue Blue Black Black

Output:
Black Green Black Green Black
Black Green Green Green Black
Blue Brown Green Brown Blue
Blue Green Green Green Blue
Yellow Yellow Gray Yellow Yellow
Purple Orange Gray Orange Purple


Here is the input grid for the test example:
