Help with Name Colors

[cokedrivers]

Hello,

What I want to do is in the chat bubbles have the units name color match their reaction to me.

Ive tried for the past 2 hours with everything I try it pops up a error.

Here is the code I'm currently using:

local function UpdateFrame(frame, guid, name)
	if not frame.text then SkinFrame(frame) end
	frame.inUse = true
	
	if settings.showSender then
		local class
		if guid ~= nil and guid ~= "" then
			_, class, _, _, _, _ = GetPlayerInfoByGUID(guid)
		end
		
		if name then
			local color = RAID_CLASS_COLORS[class] or {  r = 1, g = 1, b = 1 }
			frame.sender:SetText(("|cFF%2x%2x%2x%s|r"):format(color.r * 255, color.g * 255, color.b * 255, name))
			if frame.text:GetWidth() < frame.sender:GetWidth() then
				frame.text:SetWidth(frame.sender:GetWidth())
			end
		end
	end
end

But every thing the is a NPC or my Followers show up white text. I would like the to use my custom colors like this that is my Tooltip addon.

Tooltip Custom Colors:

CUSTOM_FACTION_BAR_COLORS = {
    [1] = {r = 1, g = 0, b = 0},
    [2] = {r = 1, g = 0, b = 0},
    [3] = {r = 1, g = 1, b = 0},
    [4] = {r = 1, g = 1, b = 0},
    [5] = {r = 0, g = 1, b = 0},
    [6] = {r = 0, g = 1, b = 0},
    [7] = {r = 0, g = 1, b = 0},
    [8] = {r = 0, g = 1, b = 0},
}

function GameTooltip_UnitColor(unit)

    local r, g, b

    if (UnitIsDead(unit) or UnitIsGhost(unit) or UnitIsTapDenied(unit)) then
        r = 0.5
        g = 0.5
        b = 0.5
    elseif (UnitIsPlayer(unit)) then
        if (UnitIsFriend(unit, 'player')) then
            local _, class = UnitClass(unit)
            if ( class ) then
                r = RAID_CLASS_COLORS[class].r
                g = RAID_CLASS_COLORS[class].g
                b = RAID_CLASS_COLORS[class].b
            else
                r = 0.60
                g = 0.60
                b = 0.60
            end
        elseif (not UnitIsFriend(unit, 'player')) then
            r = 1
            g = 0
            b = 0
        end
    elseif (UnitPlayerControlled(unit)) then
        if (UnitCanAttack(unit, 'player')) then
            if (not UnitCanAttack('player', unit)) then
                r = 157/255
                g = 197/255
                b = 255/255
            else
                r = 1
                g = 0
                b = 0
            end
        elseif (UnitCanAttack('player', unit)) then
            r = 1
            g = 1
            b = 0
        elseif (UnitIsPVP(unit)) then
            r = 0
            g = 1
            b = 0
        else
            r = 157/255
            g = 197/255
            b = 255/255
        end
    else
        local reaction = UnitReaction(unit, 'player')

        if (reaction) then
            r = CUSTOM_FACTION_BAR_COLORS[reaction].r
            g = CUSTOM_FACTION_BAR_COLORS[reaction].g
            b = CUSTOM_FACTION_BAR_COLORS[reaction].b
        else
            r = 157/255
            g = 197/255
            b = 255/255
        end
    end

    return r, g, b
end

Ive tried addin the tolltip colors to the chat buble lua and the did this line:

local color = RAID_CLASS_COLORS[class] or {  r = GameTooltip_UnitColor(unit).r, g = GameTooltip_UnitColor(unit).g, b = GameTooltip_UnitColor(unit).b }

but it give me an error thet there is no unit.

I'm not the greatest at coding but I most of the time can fumble my way threw.

Any help would be great.
Thanks
