Regarding which color cat is lucky to own, I've learned that the following are considered lucky:
yellow
Yellow cats are considered the most auspicious for attracting wealth, as yellow represents earth and symbolizes riches and prosperity, a color historically used by emperors. Yellow cats are believed to bring good fortune and prosperity, and since yellow is seen as a symbol of wealth, owning a yellow cat is considered the luckiest way to bring good fortune.
black
Black is the most auspicious color for lucky cats, and it is believed to have the ability to ward off evil spirits and dispel negative energy. If you wish for a lucky cat to have this effect, you can place it in the northwest direction of your home, which can resolve unfavorable feng shui and bring health and peace.
pink
Pink cats are considered the luckiest for attracting wealth, especially for those in relationships, as they are believed to bring increased fortune and business prosperity. Furthermore, pink symbolizes love and happiness, attracting potential partners. Therefore, pink cats are considered the most auspicious for wealth.
