I don't think of my Grandmother, she was a mean lady.  I use two colors, Black and Red, stands out and easy to identify my ball.

Is it sad that i bought a pack of 24 different coloured sharpies off Amazon as they were going cheap?!?

Anyway I've been using the dark pink/rapsberry colour most recently.

I go with the simple blue dot.  I don't like to see a bunch of marks on the ball so i try to keep it minimal.  Blue seems to stay darkest on the ball over time.  I have tired other colors like red or orange, but the ink faded much faster!

Always a Red line and a dot on each side of the number.  #1's for competitive rounds...always

I use a bright Pink Sharpie, placing dots on the ends of Titleist.  It is to honor my mom who lost her fight with breast cancer back in 2009.  She was a teacher, so I have every color marker under the sun, but I will never go away from marking my Pro V1 with pink dots.  

As you well know, having used my ball in your year end review, I put a green dot above the "T" and a blue dot below the final "t" in Titleist on each side of the ball.  Even when I'm using my personalized balls or my custom number balls (courtesy of the TT Invitational).

How about a button for all of the above? [IMG]http://i66.tinypic.com/ntb40.jpg[/IMG] I like to focus on a small dot on the inside quadrant of the ball. No matter how the ball lands, I will always have a dot to focus on.

I use two red dots right about "Titleist" on my ProV1x as well as a red putting line

Red marks for red numbers.....

A red dot next to the number.   

 I've been marking my ball with a  black and red dot ever since I saw Tin Cup 20 years ago.  The black dot was alway on the left of my number and the red on the right.

Recently, I switched to have the red dot on the left to coordinate with the TT logo.

2 black dots next to the titleist name and a black circle around the number.

Originally had a black line, have done a red line but recently switched to a blue line. Need to start putting a dot on it since my regular playing partner has taken to marking his ball in the same manner.

I use White! All the way. Lol
