Greg, I find opposite, red is mystifying but yellow and oranges are not.
Remember too that the black you are using can suck up the colors. I just remember this fact, but not which ones, hopefully someone can straighten me out. I want to say Hades eats colors, but I think Tuxedo and reg. effetre black are ok.
The newest batch of CIM phoenix is bright orange much to my dismay, and if you can get your paws on CIM Alley Cat, that was a perfect orange. I like regular effetre yellow 418. It's pretty much exact to CIM Pumpkin.
Hey! I don't see pumpkin for sale anymore...
Edit to add, here's a thread with photos of the newest phoenix
