Answer:
Something that's similar to primary colors are spices. If your going to make something sweet, then adding cinnamon and sugar is a good option. Mixing the different flavors can give you a completely new flavor while keeping a few of the main aspects of the original spices.
In a self-portrait, you'd most likely choose the three primary colors; red, blue, and yellow, although realistically speaking, as you only have red, blue, and yellow, and not black or white, you would be able to create essencially every color on the color wheel using those three, but not change the hues. This would leave you with a more abstract and vibrate portrait.
Supplies in any workforce is a must, like how a construction worker need a screwdriver, a hammer, etc., etc., and how a chef needs the kitchen.
There are some basic rules that apply to every studio; no food or water near the supplies and artwork, as it could damage and stain things, no running or fooling around, as, again, it could lead to damaging something, but the rule I think is the most important is being respectful of your space and preferences. This means that you're cautious with your surroundings, while also taking into consideration those around you. Not only that but knowing that everyone has a different preference can help someone be more logical about critic and less emotionally driven.
Hope this helps!
