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:
Black Black Black Black Gray Black Black
Black Gray Gray Red Gray Gray Black
Gray Gray Red Red Red Gray Black
Black Red Red Yellow Red Red Black
Black Gray Red Red Red Gray Gray
Black Gray Gray Red Gray Gray Black
Black Black Gray Black Black Black Black

Output:
Yellow


Example 2
Input:
Yellow Green Black Yellow Black Green Yellow
Green Yellow Red Yellow Red Yellow Green
Black Yellow Yellow Yellow Yellow Yellow Black
Black Gray Yellow Black Yellow Gray Black
Black Yellow Yellow Yellow Yellow Yellow Black
Red Yellow Yellow Black Yellow Yellow Red
Yellow Yellow Yellow Black Yellow Yellow Yellow

Output:
Yellow


Example 3
Input:
Green Green Green Black Green Green Black
Green Green Blue Blue Green Green Yellow
Black Red Red Red Red Blue Yellow
Black Black Black Black Black Blue Blue
Black Black Black Black Black Blue Red
Black Black Black Black Black Blue Black
Black Black Black Black Black Red Red

Output:
Yellow


Here is the input grid for the test example:
Input:
Black Black Black Black Green Gray Gray
Blue Gray Blue Blue Green Gray Gray
Black Gray Green Blue Yellow Green Gray
Black Green Blue Black Red Green Black
Black Gray Green Blue Yellow Green Gray
Blue Gray Blue Blue Green Gray Gray
Black Black Black Black Green Gray Gray


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