One can look up how to do the conversion and then test your work. That takes some time. Since converting back and forth between RGBA and HSLA is a generic functionality, not specific to anyone's indicators, I would suggest that NinjaTrader should provide it.
Note that this is a product suggestion, not a personal request. I have already implemented and tested it for myself. I just think that it is a common core thing that other users should not have to go through.
