I cannot find any documentation pertaining to this scenario.
Between these two lines, only sending /color with a named color works when sent via the tmi.js library.
client.say(CHANNEL_NAME, `/color Chocolate`); // This works.
client.say(CHANNEL_NAME, `/color #8697CB`); // This does not work.
As a regular user I can set my chat color to either of these.
Am I missing to an escape sequence in the message that the web interface sanitizes?
