Pink Lemonade is about as yellow as it gets, Pink Floyd is another, and Diabolic Pacman is even more yellow. Mine are bright Yellow under T5 all of those. Also 24k millie from Copps, and Aqua SD Millie is pink, Orange, and Yellow tips, Yellow Scroll coral can be very yellow, kind of Yellow highlights and light brown. Most of the other Yellows I have tried are more green than Yellow, but my wife says I am color blind!
