It seems that the oranges and yellows actually have a little variation and some have lines on their backs like the yellows mainly.
Reds are the larger variety and regular Cherry shrimp were the starter of the colors now available.
If that is your question, that there aren't as many lower quality of the orange and yellow compared to red. I think they had got a better hold (breed true) on the breeding quality before the release to mass public. But I am not as familiar with the global breeding of those. It's quite amazing the variation we now have for the Neos!!! There was barely affordable high red available 13 years ago.
The yellow and orange do have differing shell color and shell density. Hints of reddish / brownish orange I have noticed.
Here are some looking great in photos - never purchased from there just as a nice photo example

If you look up photos for high grade Orange Sakura Neocaridina Shrimp, you can get a better overall feel for what shrimp might be preferred for you to purchase.
As shrimp travel in shipping, they have stresses / loose color. Coldest winter and hottest summer time are poor times to do shrimp via mail unless you have overnight service, and then also storms as we have just seen and holidays can ruin a quick shipping plan.
If you can find locally bred and raised shrimp you may well be ahead of the game if you are getting shrimp raised with the same water parameters as what you have at your home.
Shrimp imported / sent from very special breeding facility and conditions, then shipped to your country, then shipped to a receiver (holding facility or trans shripper), and then sometimes to yet another place to be then set to you, is a LOT of stress.
Having an established tank, matured and stable is a huge help as well, no matter which way you end up receiving them.
Have you kept dwarf shrimp before?
