here is my code:

local TextChatService = game:GetService("TextChatService")
local Players = game:GetService("Players")

function toInteger(color)
	return math.floor(color.r*255)*256^2+math.floor(color.g*255)*256+math.floor(color.b*255)
end

function toHex(color)
	local int = toInteger(color)

	local current = int
	local final = ""

	local hexChar = {
		"A", "B", "C", "D", "E", "F"
	}

	repeat local remainder = current % 16
		local char = tostring(remainder)

		if remainder >= 10 then
			char = hexChar[1 + remainder - 10]
		end

		current = math.floor(current/16)
		final = final..char
	until current <= 0

	return "#"..string.reverse(final)
end

TextChatService.OnIncomingMessage = function(message: TextChatMessage)
	local props = Instance.new("TextChatMessageProperties")

	if message.TextSource then
		local player = Players:GetPlayerByUserId(message.TextSource.UserId)
		if game:GetService("MarketplaceService"):UserOwnsGamePassAsync(player.UserId, 839718134) then
			local value = script:WaitForChild("V.I.D")
			
			props.PrefixText = "<font color='"..toHex(value:WaitForChild("Color").Value).."'>["..value.Name.."]</font> " .. message.PrefixText --these break
		end
			
		if player.UserId == 869133154 then
			local value = script:WaitForChild("OWNER")

			props.PrefixText = "<font color='"..toHex(value:WaitForChild("Color").Value).."'>["..value.Name.."]</font> " .. message.PrefixText --these break
		end
		
		if player.UserId == 647598508 then
			local value = script:WaitForChild("DEVELOPER")

			props.PrefixText = "<font color='"..toHex(value:WaitForChild("Color").Value).."'>["..value.Name.."]</font> " .. message.PrefixText --these break
		end
	end

	return props	
end
