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:
Orange Orange Pink Pink Orange Orange
Gray Orange Blue Blue Orange Gray
Blue Blue Blue Blue Blue Blue
Yellow Yellow Gray Gray Yellow Yellow

Output:
Orange Orange Pink Pink Orange Gray
Gray Orange Blue Blue Orange Orange
Blue Blue Blue Blue Pink Blue
Yellow Yellow Gray Gray Pink Blue


Example 2
Input:
Gray Gray Brown Gray Pink Pink
Gray Pink Gray Gray Gray Green
Gray Pink Pink Brown Green Pink
Gray Gray Green Brown Brown Pink

Output:
Gray Gray Brown Gray Gray Gray
Gray Pink Gray Gray Gray Pink
Gray Pink Pink Brown Brown Gray
Gray Gray Green Brown Gray Gray


Example 3
Input:
Purple Purple Blue Blue Purple Purple
Purple Purple Brown Brown Purple Purple
Purple Purple Blue Blue Purple Purple
Purple Purple Blue Blue Purple Purple

Output:
Purple Purple Blue Blue Purple Purple
Purple Purple Brown Brown Purple Purple
Purple Purple Blue Blue Blue Brown
Purple Purple Blue Blue Blue Brown


Here is the input grid for the test example:
Input:
