After some thought, I've downgraded Samurai to dark blue. It's an effective subclass, no doubt (especially past Lv. 10), but Battle Masters and Eldritch Knights both have their ways of getting advantage on a lot of their attacks (even if not with the 100% reliability of Fighting Spirit), and besides that have a lot more nifty tricks up their sleeve. So, can't rate Samurai quite on their level.
Also downgraded Arcane Archer to black. Only 2 uses per short rest just doesn't seem adequate beyond the earliest levels, and Ever-Ready Shot probably should've come around Lv. 10 instead of 15.
And on that note I now have no arguments with your list. I would say archer should be red but that would be my immature side coming through wishing it had been a different archetype for fighter (monster hunter)
