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:
Red
Pink
Brown
Green
Blue
Yellow
Orange
Gray

Output:
Red


Example 2
Input:
Pink
Blue
Purple
Brown
Red
Yellow
Green

Output:
Pink


Example 3
Input:
Brown
Blue
Green
Purple
Orange
Yellow
Red

Output:
Brown


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


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