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:
Orange Orange Orange Orange Orange Orange Orange Orange
Black Green Black Orange Purple Purple Black Purple
Black Black Black Purple Black Black Blue Black
Brown Brown Orange Brown Brown Yellow Brown Brown
Pink Pink Pink Brown Pink Pink Pink Pink
Black Black Black Black Black Green Black Black
