How to change this color please?

Thx for advance.

Hi guys,

I found solution.

local function PaintNotches(x, y, w, h, num)
	if not num then return end

	local space = w / num

	for i=0, num do
		surface.DrawRect(x + i * space, y + 4, 1, 5)
	end
end

local DNumSlider = vgui.Create("DNumSlider")
DNumSlider:SetPos(50, 50)
DNumSlider:SetSize(200, 20)
DNumSlider:SetMin(0)
DNumSlider:SetMax(10)
DNumSlider.Slider.Paint = function(self, w, h)
	surface.SetDrawColor(Color(255, 255, 255, 100)) -- Color slider gradient
	surface.DrawRect(8, h / 2 - 1, w - 15, 1)

	PaintNotches(8, h / 2 - 1, w - 16, 1, self.m_iNotches)
end
