CAPRICORN (Dec. 22-Jan. 19): What combination of colors makes the most vivid visual impact? Psychologists say it's black on yellow. Together they arrest the eye, command attention and activate a readiness to respond. According to my astrological omen-reading, this is the effect you can and should have in the weeks ahead. Time to draw the best kind of attention to yourself. You have a right and a duty to galvanize folks with the power of your presence. Whether you wear yellow clothes with black highlights is optional as long as you cultivate a similar potency.
