But they apparently matched the TOS paint.
"Deverell reveals, she had to go through multiple color studies to match what is known as “Enterprise Red” (...) “There is a distinct Enterprise Red,” Deverell explains. “I actually took that color from the CBS archives ... and it was orange! In certain episodes of TOS, the red became more of an orange. I went insane looking at different color tests. It is red. But, in canon, it’s also orange."

There is another interview:

Then, I really wanted to color-code. So, I was playing a lot with the colors of the
Enterprise. There are actually variations [of the red-orange] in the
Enterprises . That's very distinct, and I went through the archives at CBS to look at those colors and try and match them, but in a new way. We were bringing in the
Discovery feel, but also using materials and methods of building it that were new to us, like metal powder coating — metal pieces that are powder-coated create a really rich color and strong basis to build the set. We experimented with it on the
Enterprise, and I think we’re going to use it more in
Star Trek. It looks more like a ship than just using wood and plaster."
We couldn’t help but laugh out loud when Georgiou walked in and complained, “Orange? Really? Ick!" Was that scripted, or ad-libbed by Michelle Yeoh? And, either way, what was your reaction?
TD: That was scripted. The Enterprise had different colors. They changed it over time. The way it was lit, sometimes it looked really orange and sometimes it looked very red. The orange we’d picked, which was the original orange, was really red.
[So] I actually went to the writers and said, "I'm uncomfortable with this line." I did this whole layout of the different oranges and the red we decided we were using, and all of that. We had powder-coated this metal in this red, so there was no going back. I went on and on and on. Alex Kurtzman wrote back, saying, "This is why we love you, Tamara. It's okay. We're gonna say orange. It's okay, don't worry." It was just a funny story. I loved Michelle’s line, but to me, like any production designer would think, it was all about, “Do I have the right color?”

My take on it and the bit you posted is that they looked at the TOS colours and took an "orange" variation most people would call red. And thanks to the new material (metal powder coating) and better lightning and cameras, it looks totally red without any kind of orangeness on TV like it did on TOS here and there.
