In Feng Shui, koi are believed to attract prosperity, wealth, and positive energy. The vibrant colors of koi are also associated with different aspects of life, such as red for love and courage, gold for wealth, and black for overcoming adversity. Painting koi captures these auspicious qualities, making the artwork not only visually appealing but also a meaningful expression of luck, success, and resilience. Having koi paintings in a space is thought to invite these beneficial energies into one's life, making the art both decorative and spiritually significant.
