I had yellow nails and I loved it! :L I tried Mellow Yellow a while ago and I liked it so much, but I failed with nail art so I had to remove it. :D
I added 2 coats, I thought it was OK but while watching this pictures I know I'd have to add another one. :$ Another pretty shade from Essence, looks so fresh and perfect for summer. :)
Here's a bottle comparison with mini Orly - Lemonade. They're very close, Essence is a tiny bit more yellow, but of course you can't see that on this picture. :D I don't think you need both though.
Do you wear yellow on your nails?What is your favorite yellow nail polish?
