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:
Yellow Purple Pink Pink Pink
Purple Orange Blue Orange Brown
Pink Brown Blue Pink Orange
Brown Gray Gray Gray Purple
Yellow Purple Pink Pink Red

Gray


Here is the input grid for the test example:
Input:
Blue Red Purple Purple Red
Orange Gray Orange Purple Yellow
Purple Orange Purple Pink Gray
Orange Gray Orange Gray Brown
