Here is the first picture *ever* (that I know of, definitely the first yellow one) Supershrimp (Opae ula) color mutation in captivity: 
I discovered this shrimp and two others in one of my tanks just about 5 days ago. This one is a female (and here you can clearly see the "dark spot", which is eggs in the ovaries), and I believe that I have two males. If I can ever find them again among the 1000+ shrimp in the same tank, I will set up a new tank and try to breed this color variety (which is a long term project with Supershrimp). I'm pretty excited about this. Imagine a tank full of yellow Supershrimp right next to a tank with red Supershrimp! Or a mixed tank, yellow and red intermingling! This is great! Who knows what color varieties I will discover in the future if I actually take a closer look at every single tank I have. I, for one, would love to see some blue Supershrimp in the future.
This is, however, not the first mutation I have discovered in my tanks. I discovered completely white (see-through white..similar to male Snowball shrimp) Supershrimp with bright green eggs years ago already, and I believe I still have some swimming around in my tanks (if I can find them). I may have a picture somewhere, too, I'll have to dig around. There are also some pink shrimp swimming around in some of my tanks...not just pale red, literally *pink*. I never bothered breeding those other mutations, but now that I discovered the yellow mutation, I may just go ahead and set up a tank for the white mutation (and maybe the pink one), too. Let's see what happens....
