Nice Mike D!

6 Red Dots in the dimples next to the number on my Pro V1!

#MyProV1

I use red because it matches all my StL Cardinals gear!

Black.

3 dots in a triangle above the Titleist Branding on both sides of the ball.

I switch it up between black, blue, and green.

I've never used a sharpie to mark my ball but i'm thinking about changing it up..  I'm going to start off with a sleeve and give it to my boys.  I'll them doodle all over the ball, let it dry and then I'll take those sleeves with me to the course...

We'll see how that goes...  I'll be sure to post some pics if that happens.. 

Just like Duffy Waldorf did years ago...

My usual combination is a black sharpie down the side stamp & a red circle of dots around the #1 on the Pro V1.

I  tried giving it to my daughter to "decorate" and it came back to me with EVERY single dimple colored in multiple colors.  I couldn't even tell what kind of ball it was.  Now she understands to just put her favorite sign on ONE side of the ball, not all over it. 

Green is my go too color, its rare anyone uses it making finding my ball easier.

Always mark my Pro V1x with Florescent Orange Sharpie. All my buddies in my playing group mark their Titleist Pro V's and Pro V1x's with red, green or black so I decided on being different. I was playing in a NYS amateur event up in Syracuse, NY when a fellow group member played another group member's ball by mistake because they both had marked their Pro V's with black dots and accrued a penalty for doing so! Lesson Learned!

Usually Black, but I do have an assortment of colors in my bag. I am partial to the Sharpie Mini's. I have several hooked to a keyring, this helps me to keep them organized.

Always a number 2 for competitive rounds, and never anything other than blue in support of the Wildcats. #BBN

Blue. Always. 

I put a black line under Titleist and a dot at the end :)

Green Shamrock and a single green dot on the opposite side. Luckily haven't had the same problem as Don.

blue for me 

I no longer sharpie my golf balls.  I order custom numbered with personalization, last name on them.  But, before I started this, I always carried, green, blue, red and black sharpies.  The color wasn't a big deal, but how and where was, initials are TF, so I combined them into 1 symbol, using a T, then adding the middle of the F to the middle of the T.  Always to the right of the number. 

Blue line under Titleist and above the number for me.  

I mark my ball in a few different ways.  When I need some luck i go with the Green clover below the number.  When I am feeling good and things are rolling well I put a simple Red dot over the number.  When I am playing with people I dont really know, and I someone is playing the same ball as me I put a blue line thru the Pro V1 X on the side and two dots by the number.  When I am playing in a tournament I mark my ball with the Mizzou Varsity M stamp my wife had made for me.  Also, I have my name on the side of all my Pro V1's.  So there's a good chance a lot of guys at my club have a many of my balls, marked different way, in their bags after I lose them!

Gotta go green.  Green like the fairway, green like the... well... green, and green like the cash I'm trying to win!

No comments from Speedy on the "cash I'm trying to win" part....

I circle the number in red, both sides.

A red dot above the capital T and a blue dot below the last t on both sides.  This is represent the colors of  both US and the Dutch flags.

I've always just colored in 1 blue dimple closest to each number.

Black dot underneath the number.

Purple and gold metallic are my favs.
