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:
Purple Purple Purple Purple Gray
Gray Gray Gray Purple Gray
Purple Purple Purple Purple Purple
Purple Purple Gray Purple Purple

Output:
Purple Gray Gray Gray Gray
Purple Gray Purple Purple Purple
Gray Gray Gray Gray Gray

Purple Brown Purple Purple Purple


Here is the input grid for the test example:
Input:
