A suitcase is an article with wheels, which is used to transport what people need to far away places. The color of the suitcase depends on personal preferences and cultural beliefs.
Pigs are a common animal and are regarded as mascots and symbols of wealth. If you want to increase wealth and good luck, you can choose the pattern or color of the pig.
But if you just want to choose an ordinary suitcase, you can choose your favorite color and pattern, or you can choose other colors according to your personal preference.
In short, choosing the color and pattern of luggage depends on personal preferences and cultural beliefs, not on the zodiac or color.
