I just want to contribute and maybe make the life easier for some, I made a NCS/RAL converter with the help of ChatGPT. It seems to work with the colors i tried.
With RAL, you have to build your desired dictionary of colors or copy from someone who did. NCS colors are converted.
It works on Shapediver also, it contains custom code so you may need a paid subscription.
Disclaimer, the color may not be 100% accurate.
