Nice to have someone so jolly on here
There are various pellets on the market that have a colour enhancing chemical added. One such product is Hikari Cichlid Gold. I have fed this to my Oscars on and off for quite a few years now and to be perfectly honest with you, I couldn't honestly say I noticed any difference in their colour. But then again, I do very good they are and don't feed them on this pellet all the time. However, I know people have said it enhanced the colours on their Oscars so I imagine it works in some cases. Just get some and try it and see what happens. I have never actually been that keen on trying to artificially change the colour of my fish. I am quite happy with the colour they are without having to feed them chemicals to change their colour. Don't let this put you off though, Hikari cichlids gold in a very good quality food and Oscars really do like it.
