What is the opinion of Reddit about the
Realforce R2&R2TL Compatibility Colour Point Keycap Set (Green)?

I looked around on Amazon which isn’t the best place for keyboard stuff but it is probably out there you would just need to do some digging. This should be what you are looking for bits it’s very expensive https://www.amazon.com/Realforce-Compatibility-Colour-Point-Keycap/dp/B0831B3Q25/ref=mp_s_a_1_11?dchild=1&keywords=green%2Baccent%2Bkeycaps&qid=1624263935&sr=8-11&th=1&psc=1

and this you could buy and just use the green caps you want and it’s way cheaper https://www.amazon.com/MOHALIKO-Keycaps-Universal-Mechanical-Keyboard/dp/B08G49CHYZ/ref=mp_s_a_1_3?dchild=1&keywords=green+accent+keycaps&qid=1624264052&sr=8-3 make sure they match the keycaps profile your using or it will look wonky.
