Is there a name for this color?  The one on the left.    I was only able to find one other bait with a similar coloring (Bomber Fat free) and they called it "threadfin shad."

If it's like the bomber fat free shad in threads in shad, I always called it rainbow. I dont know the correct terminology for it, I always used pop-rs in that same color 

pink lemonade is what its  called sometimes

Sometimes it's called Easter Egg.

Lol. It's called whatever you can think of that's pink and yellow apparently 

It looks like a darker version of ghost minnow, most companies have a color similar, red with some yellow and silver flash....I guess it is more Pink, but that is a standard color, exact replicas may be tough to find, but I am sure you can find close enough, Rapala has a ton of colors like that, Bomber, most of the G-Finish style colors, even bass pro or house brand baits.

Many lures have orange or yellow on the belly and a pink or red tone, Clown would be similar but offer more contrast, but the key to that color is the flash in the translucent body, R2Sea makes alot of colors like that for example. Bomber just released about 30 new colors for the long A series putting the total amount of colors on Pradco alone at about 50 plus you can find tons of rare colors on Ebay.
