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