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 Yellow Yellow Black Pink Pink
Gray Gray Black Yellow Yellow Black Pink Pink
Gray Gray Black Black Black Black Pink Pink
Black Black Orange Orange Purple Purple Pink Pink
Brown Brown Orange Orange Purple Purple Black Black
Brown Brown Yellow Yellow Black Purple Purple Black
