system
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
Orange Pink

Output:
Orange Orange Yellow Yellow
Orange Orange Yellow Yellow
Pink Pink Purple Purple
Pink Pink Purple Purple


Example 2
Input:
Green Pink
Orange Yellow

Output:
Orange Orange Green Green
Orange Orange Green Green
Yellow Yellow Pink Pink
Yellow Yellow Pink Pink


Example 3
Input:
Green Orange
Gray Brown

Output:
Gray Gray Green Green
Gray Gray Green Green
Brown Brown Orange Orange
Brown Brown Orange Orange


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


Directly provide the output grids corresponding to the given test input grids, based on the patterns observed in the reference examples.
