it makes sense if you understand the background of lisciencing. It's been a problem throughout star trek. everything from The Motion Picture to the last episode of Voyager belongs to Paramount. That includes the klingon look. The old look belongs to DesiLou productions. But roddenberry owned the word. the name and the language. So in order to make the klingons look like TNG/DS9, it would cost CBS. Theyed have to pay paramount. Which doesn't seem like a big deal because both are owned by viavcom, but thats where it comes from. Thats why starting with the reboot movies the klingons were changed as well as the uniforms. In the reboot movies, although they use the gold/blue/red scheme, if you look at the uniforms they are different. same goes for the bridge layout and the technology. CBS can't make Discovery tech look like TOS because that belongs to desilou. So, since they had to change the look of everything, they went back to the begining. Roddenberry wanted the klingons to look the way they do in Discovery. He wanted the romulans to look like the way the remans ended up looking. But the low budget of TOS ended up having the klingons with bushy eyebrows, shoepolish on the face, and foomanchu's. And the romuland looked vulcan because they already had ears made. The blue uniforms are meant to look like an evolution from ST:ENT -> Garth of Izar's uniform -> Discovery. I don't mind the changes. And i am somewhat enjoying Discovery. Certainly better than that first season of Enterprise. But this in not prime universe. It's a reboot regardless of what they say.
