LOVE the new augment for Khora! (Assuming it's not intentional) this still is not fixed for the Vaykor Sydon. The lens flare for the radial blind stacks is still stuck on the default white even with dual colors unlocked.
Not sure if bug or feature, but after testing it out, the glow effect on the Vaykor Sydon does not change with either of the energy color options. And that's if I change dual color options on both the warframe and the weapon itself (it stays the default white.) If it's a feature, it would be cool for the radial blind stack glow to match the trident energy color. This way it doesn't clash and we can all have a rainbow of glowing tridents.
