Color3 and Brickcolor switching??

I'm trying to make a team changing menu thingy, but when I try to change the team colour, it says

18:09:23.069 - ServerScriptService.ChangeTeam:6: bad argument #1 to 'new' (Color3 expected, got BrickColor)

So I thought "Alright, a bit odd. But I'll change it to a Color3. After all, that's what the error said to." I change it, and when I run it, it has the audacity to print

18:12:26.480 - ServerScriptService.ChangeTeam:6: bad argument #3 to 'TeamColor' (BrickColor expected, got Color3)

Also, the print I put printed out a string value. AKA the BrickColor value.

Here's the code. This has stumped me..

local MMS = game:GetService("MarketplaceService")

game.ReplicatedStorage.ChangeTeam.OnServerEvent:Connect(function(plr, teamColor, free, passID)
	print(teamColor)
	if free then
		plr.TeamColor = Color3.new(teamColor) -- you can also say BrickColor.new(teamColor)
		plr:LoadCharacter()
	elseif not free then -- ignore this and below. it's irrelevent
		if MMS:UserOwnsGamePassAsync(plr.UserId, passID) then
			plr.TeamColor = BrickColor.new(teamColor) 
			plr:LoadCharacter()
		end
	end
end)
