Can someone list all of the Dots made back in the day? Currently I have a Wine U Dot, U2 (original not "classic"), and two Yellow Dots. Off the top of my head, I know theres a Black U Dot, Blue Dot, and a White Dot (currently out). Any others that I'm missing? Believe there's a blue ball that came out around the same time as the Yellow Dot.

There's also the original Black U-Dot, the Gold Dot, and the Slate Grey U-Dot.

White Dot
Blue Dot
Red Dot
Yellow Dot
Yellow Dot (the later blue version)
Orange Dot
Black Knight (solid black ball with a white dot, but slightly harder than a regular white dot) This was basically a White Dot with a special name.
Gold Dot (This ball was pearlized urethane in several colors)
Wine U-Dot
Black U-Dot
Slate U-Dot

 The U² and the Vector series also had the U logo in the center ring, but weren't officially called "Dot" balls.

 The Sur D may have been considered part of the "Dot" series, but I have never heard it referred to as that. It is always denoted by the name "Sur D" on it.

 Can't think of anymore right off.  I was a big fan of the silver and carmel White Dots.

 P.S. There was also the "New formula" Yellow Dots that they tried in the late 1980's, but they sucked, and C300 soon went back to using the old formula again. The "New firmula" balls looked much different than the regular ones. They were a dullish finish, and sort of resembled the turdish looking Orange Dot balls. I had one and hated it.

I still have a Bud II (black u-dot 2),

After they banned the origional Shur D , Columbia reformulated the cover and rereleased it as the red dot Shur D. It was the same cover as the Caramel white dot. The blue white dot became very popular for awhile because it took the acitone bath better than the other colors.

Was the ORIGINAL blue dot only in silver?  I could have sworn they had another color.
