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.
The symbols would be considered pop out because of the color scheme. The color scheme makes the colors pop to be rememberable.
