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

Output:
Red


Example 2
Input:
Blue Green Pink Purple
Gray Orange Red Red
Green Yellow Pink Blue
Red Blue Yellow Orange

Output:
Red


Example 3
Input:
Gray Orange Yellow Purple
Brown Red Pink Brown
Green Orange Green Orange
Yellow Red Blue Brown

Output:
Red


Here is the input grid for the test example:
Input:
Brown Yellow Blue Brown
Yellow Gray Yellow Orange
Blue Green Orange Pink
Pink Blue Pink Orange


Directly provide the output grids corresponding to the given test input grids, based on the patterns observed in the reference examples.
