To what looks like the first question a foundation for pop music is to have a strong bace, then add some treble and vocals. If I personally was making a self portrait I would use purple brown and my skin color. I chose purple because its my favorite color and I like to dye my hair it. I chose brown because its the color of my roots and eyes. And obviously the color of my skin because well it would probably look weird without skin lol. I think the dark colors may make it look a bit depressing but oh well. A chef needs serten tools to cook like knifes, pans and measuring utensils, like cups and tablespoons/teaspoons. Sadly I can't answer the last two. Hope the other answers helped though.
