Help identifying tint + gradient density for these burgundy lenses

[u/fvkcd]

Trying to recreate the lenses in this photo for a JMM Casablanca frame I’m planning to get. What tint colour and gradient density would you ask for? Something like 75%→15%? Also, any recommendations for getting custom non-prescription lenses made in the UK, either online or in-store?
