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:
Gray Brown Yellow Red Blue
Red Black Black Black Black
Green Black Black Black Black
Blue Black Black Gray Gray
Gray Black Black Gray Gray

Output:
Gray


Example 2
Input:
Yellow Purple Brown Orange Red
Blue Black Black Black Black
Purple Black Black Black Black
Red Black Black Brown Brown
Gray Black Black Brown Brown

Output:
Gray


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

Output:
Pink


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


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