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:
Pink Pink Black Black Black Black Black Black Black Black Black
Pink Pink Black Black Black Black Blue Blue Black Black Black
Pink Pink Blue Blue Black Black Blue Blue Black Black Black
Black Black Blue Blue Black Blue Blue Black Black Black Black
Black Black Black Black Black Black Black Black Black Black Black
Black Black Black Black Black Black Pink Pink Black Black Black
Black Black Black Black Black Black Black Black Black Black Black

Output:
Pink


Example 2
Input:
Orange Orange Black Green Green Green Black
