Paint look up alternatives?

I'm looking to start a repairing cars bodyworks, kinda as a hobby kinda as a side business, I have previous experiences with painting/painting softwares since I work in an adjacent industry, so I don't want to buy OEM paints already made but to mix and match my own since I'm used to it and like the process.

Does anyone know any alternatives to PPG paint manager xi for example? I don't mind if I have to pay for the system (to my understanding PPG can be bought only for the color look up feature, but I don't find any information about getting it as an individual) also using the system at my workplace might be difficult since I'm not part of that department so I'm looking for something that I could have on my personal computers and stuff.

I honestly don't need anything other than the color lookup tools for mixing, anything else would be over the top for something as a hobby.
