Here's a pic from my old phone. It was at a marine lab. I don't have an ID on it, but it might be the kind of yellow you're looking for! Note that the other yellow coral in the pic is a yellow scroll for comparison.
Here is a frag of Pink lemonade I just cut for my other tank. I cannot get the true color of the yellow easily but it is bright with nice pinkish red polyps
I have BC Teen Wolf that has changed to almost a solid yellow with red polyps. I keep it at over 650 par. When I first got it had yellow coralites with purple in between and red polyps. I lost my phone or I would post a before pic but here is a daylight and blue pic.
I also feel that RR Pink Floyd is pretty yellow. Daylight pic
Note the bottom front of the Pikachu. I bottomed out nitrates resulting in the back of the coral having burnt tips and turning slightly green. Prior to that, the entire coral was same yellow as the bottom front. Par is about 700.
Those yellow tip branching porites can be very solid yellow under natural light or under lots of light. One of my first corals and it made it through many tank issues. Best part for me was it didn’t grow like a weed which was nice. Not many sps lovers keep this coral but I think it would look great in most any tank. Even when it’s green with barely any yellow in the tips it’s still a different look.
Yes, it is canary yellow under white light, but really washes out with more blues.
There is a yellow NPS coral out there too. The name escapes me right now...
