How do you disable coloured names when chatting whilst in a team?

[FarLands_orBest (Cygnus)]

Really simple question but I can’t for the love of god, find the answer anywhere online. I simply want to make it so that when a player chats, the colour of their username in chat isn’t changed by the team that they’re in.

Compared to the legacy chat system, TextChatService does not provide or expose a convenient method for achieving your goal. To solve this problem, I temporarily reverted to the legacy chat system so I could access its source code. In it contains the algorithm responsible for associating a colour to a username. After forking the algorithm, cleaning it up, and modifying it to function best in this situation, I used it to override the prefix text colour of incoming TextChatMessages. Altogether:

--!strict
local TextChatService = game:GetService("TextChatService")
local Players         = game:GetService("Players")



local NAME_TAG_RICH_TEXT = `<font color="#%s">%s</font>`

local NAME_COLORS = {
	Color3.fromRGB(253, 41, 67),
	Color3.fromRGB(1, 162, 255),
	Color3.fromRGB(2, 184, 87),

	BrickColor.new("Bright violet").Color,
	BrickColor.new("Bright orange").Color,
	BrickColor.new("Bright yellow").Color,
	BrickColor.new("Light reddish violet").Color,
	BrickColor.new("Brick yellow").Color,
}



local function getUsernameValue(username: string): number
	local length = #username
	local value  = 0

	for index, character in string.split(username, "") do
		local characterWeight = string.byte(character)
		local inverseIndex    = length - index + 1

		if length % 2 == 1 then
			inverseIndex -= 1
		end

		if inverseIndex % 4 >= 2 then
			characterWeight = -characterWeight
		end

		value += characterWeight
	end

	return value
end

local function getUsernameColorHex(username: string): string
	local color = NAME_COLORS[(getUsernameValue(username) % #NAME_COLORS) + 1]
	
	return color:ToHex()
end

local function onIncomingMessage(message: TextChatMessage)
	if not message.TextSource then
		return
	end
	
	local player = Players:GetPlayerByUserId(message.TextSource.UserId)
	if not player then
		return
	end
	
	local textChatMessageProperties = Instance.new("TextChatMessageProperties")
	
	textChatMessageProperties.PrefixText = NAME_TAG_RICH_TEXT:format(
		getUsernameColorHex(player.Name),
		message.PrefixText
	)
	
	return textChatMessageProperties
end



TextChatService.OnIncomingMessage = onIncomingMessage

wow I never would have managed this myself. tysm!
