No, if I buy LEDs that expensive I’m going to do it properly with a current-limited power supply which is very expensive. Using voltage to control LEDs is living dangerously and these are very pricey LEDs.

I want a system that will actually survive for a few years not a one-time experiment.

I tried finding green, with no success. Most of those markers/felt tips are more than 10 years old, that's why they are a bit dirty. I used them in primary school, and I still have them.

Interestingly, there are some faint purples.

I like the overall palette that you are getting here. It’s pretty.
