In golf, there are certain lucky symbols. Some major ones include a horseshoe shaped accessories or the green shaped like it, a four leaf clover in the rough, and a ladybug on your club.
With some believing all this to be a superstitions, some believe it really brings them luck, at least with their shots.
Some stars like Tiger Wood would always wear a red shirt at the final round ever since 1996. Same with Paula Creamer who would wear her color as a final round dress code.
Whether it's the lucky color, lucky ball, lucky club or etc, if it provides positive energy to you, that's what matters. As many believe, having positive superstition can improve your shots and your game.
