Color matrixes might not be correct for 'protanopia' vs 'deutranopia'

[JLansey]

The code runs great thanks very much but it seems that the it isn't precise when it comes to distinguishing the subtle difference between 'protanopia' vs 'deutranopia'

To test it I ran the Farnsworth D-15 color blind test plates and the data doesn't match what is expected. For example, considering deutranopia, 6 should be confused with 9, and 3 should be confused with 12. But in the following image simulating deutranopia 6 kind of looks like 9 and 3 is definitely distinguishable from 12. Note I grabbed the colors for the Farnsworth from https://www.color-blindness.com/color-arrangement-test/ so perhaps I'm using the wrong colors and that is the issue - but other simulators do match what is expected, for example: https://pilestone.com/pages/color-blindness-simulator-1

Anyway thanks for the great tool - would love to hear if I've made a mistake here with my understanding or otherwise.

Thanks so much!
