I am just a bit confused whether cherry shrimp colour up with age or are born like that. Most info out there suggests young cherrys have little colour but to me it doesn't look like it.
Here are a couple of mine below that were very young on these pictures, taken with zoom and macro to actually make something visible, and they aren't colourless, although they got siblings that were colourless then and still are.

For example, these two below are grown up adult males, totally colourless, although I have pinkish males that are not as red as females, but have body colour of some kind.

There are a lot of factors that affect coloration maturity is one of them, stress, gender, water issues etc. In order to figure out the cause I need some info: What are your Parameters? what other critters are in the tank with the shrimp?

There are corydoras fry in the tank and the shrimp but soon enough it will be just the shrimp. I don't have any fancy shrimp as my water is hard for the sorts of crystals, etc..
Not sure which parameters you need but here are the main ones I've measured:
ammonia-0
nitrite-0
nitrAte-5-10ppm
ph-7.4ppm
TDS-280ppm
temp-25C(77)

Those shrimplets look normal to me. My painted fire red look similar to these. They start from transparent orange to what you have, then to wine red then opaque bright red.
