Red is the color of fire and blood, so it is associated with energy, danger, strength, power, determination as well as passion, desire, and love.
It's not really like a Capricorn to wear a lot of red, but those who know its secretly a very sexually powerful color for them to wear sure do! Try it these ways:
-A solid, brick-red top. For women, a fitted blouse. Men, a class t-shirt works best, alone or under a coat.
-Your accessories. From your watch to jewelry to your tie or a scarf.
-Makeup! The classic red lip is very Capricorn!
-Still shy? Wear red underwear... only a very special person gets to see, but you will radiate the heat of the color anyway.
