Why does these values not change?

I'm working on a Morphroom with a GUI that allows for the player to input a custom VertexColor. The issue now is that the Values arnt changing.

In studio I've manually changed R,G,B to see if the whole script works. It does somewhat except the values arnt changing.

Display.Click.MouseClick:Connect(function(player)
    local HairColor = player.DATA_.HairColor
    local R = HairColor.Red.Value
    local G = HairColor.Green.Value
    local B = HairColor.Blue.Value
    local colorstring = tostring(Vector3.new(R,G,B))

    print(colorstring)
    Display.SurfaceGui.Vertex.Text = tostring(Vector3.new(R,G,B))
end)

It keeps coming out as 1,1,1 even if I changed R,G, or B. Is there something I'm doing wrong or missing?
