Theme UI - Shouldn't Sigvald use the Colour Named After Him?

Gorgo_Primus#7326

I know CA decided to make him Undivided with a heavy lean towards Slaanesh rather than make a new one and slot him in as pure Slaanesh, and that's fine and I won't complain. But can he at least get a Sigvald Burgundy (Purple) Theme UI? It's his colour, figuratively and literally, and seeing Khorne Red everywhere when I play as him is kind of off-putting in terms of immersion. You guys named the UI theme after the colour he adores and uses on his banners, and he already leans heavily Slaanesh anyways, so can he please get a UI swap?

I have no idea why this was down voted
