Unwillingly

Aqua - pretty alright, typical for elves, specifically high elves or dark elves 8/10

Blue - decent, kind of hard to read with shaders, not seen many people with this 6/10

Dark Aqua - shamefully i have not seen many people with this either, actually a underrated chat colour 9/10

Dark Blue - possibly the WORST chat colour, hard to read with and without shaders and just makes rping awful with this colour 1/10

Dark Gray - similar to dark blue but not as bad of an offender, very very rarely see people with this colour, typically its dark magic players that use it. 3/10

Dark Green - used by a lot of highlander humans, wood elves and dwarves typical for humans in agricultural settings. pretty decent and common chat colour. 7/10

Dark Purple - despite being called "dark" it is quite vibrant, another common one, this one is used a lot by dark elves and dark magic characters. 8/10.

Dark Red - for the edgelords, whoever is emoting at you with this is either a knight/soldier, a bandit or a norlander. no inbetween. pretty standard. 7/10. 

Gold - decent chat colour, feels kind of flat in my opinion compared to some of the other ones but gets the job done. 6/10

Green - really good chat colour but imo is too vibrant sometimes, personally i use this one but i hadn't put much thought into using it i just like using uncommon ones. i dub thee, traveller green. 7/10

Light Purple - makes you look like a pink tag and i have to double check every time you emote with this, stop using it please. 4/10

Red - similar to dark red but slightly less edgy. used by a lot of people. 6/10.

Yellow - another very underrated one but suffers from a lot of the problems that "green" does too, never personally seen this one used ever so i might start using this after i press submit on this. 8/10.

yellow, reminds me of aegis.
