Finally got it, had to play with the textures also. Thanks for the help!

function Border:OnUpdate(parent, unit, status)
	if status then
		parent:SetBeautyBorderTexture('white')
		parent:SetBeautyBorderColor(status:GetColor(unit))
	else
		parent:SetBeautyBorderTexture('default')
		parent:SetBeautyBorderColor(1,1,1)
	end
end
