Need help with my yellow

I don't know if it's me? I can't ever get my yellows to POP , do you guys have a secret you can share that makes your yellow pop! Thanks LB

I don't use a plain yellow for anything but tweaking other colors. You could try adding just a dab of gold hi lite to it to help run surface light around for you. Maybe a drop of chartreuse? Maybe a drop of white to get the lemon out of it?
