If you were born between December 22 and January 20th, you fall under the astrological sign of Capricorn. An earth sign, people born under Capricorn are known for their solid, dependable personalities. Capricorns are steady as a rock, and since they are so grounded their best colors tend to run in shades of brown through black.
That's not to say that Capricorns aren't colorful. Their sudden bouts of wit can make them seem rather capricious, but this only adds dimension to their personalities.
So, are Capricorns really suited to tattoos? Yes, and ideally so. Once Caps make a decision, they stick by it; this is exactly what any true tat enthusiast does when committing to a design.
