Luck-Boosting Colors: Earth tones such as yellows, beiges, taupes, and also purple (the "Feng Shui beige")
Your kua number is 7 so that means your element is metal. Wear colors representing metallics, such as white or shades of silver. In Feng Shui, earth creates metal so if you want to boost your luck, wear yellows, beiges or purple. Combining these colors is a great idea! White and yellow, or purple and silver, are lucky color combinations.
