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:
Brown Brown Brown Brown Brown Brown Brown Brown Brown Brown Brown Brown
Brown Yellow Yellow Yellow Yellow Yellow Yellow Yellow Yellow Yellow Yellow Brown
Brown Yellow Blue Blue Blue Blue Blue Blue Blue Blue Yellow Brown
Brown Yellow Blue Purple Purple Purple Purple Purple Purple Blue Yellow Brown
Brown Yellow Blue Purple Purple Purple Purple Purple Purple Blue Yellow Brown
Brown Yellow Blue Blue Blue Blue Blue Blue Blue Blue Yellow Brown
Brown Yellow Yellow Yellow Yellow Yellow Yellow Yellow Yellow Yellow Yellow Brown
Brown Brown Brown Brown Brown Brown Brown Brown Brown Brown Brown Brown

Output:
Brown
Yellow
Blue
Purple
