Looks like you got it! You just want the basics. Just also keep in mind that sometimes there are some color tops used that are "lab or in-house" specific. So ask your supervisor for their preferences once you get there. It's also a great way to introduce yourself, show sincere interest and professionalism. "Before I get started, I'd like to know whether you are using certain in-house or lab specific preferred collectin tubes for certain tests. Is there a list of tube top colors I can refer to?" That's all you have to say. I bet that will make a big impression. I wonder how many ask this before-hand.

According to a phlebotomy site, they go in this order:
yellow-blood cultures, SPS sterile
Lt. Blue-buffered sodium citrate
Red/Tiger Top-gel separator tube
Green-heparin and light green-sodium or lithium with or without separators.
Lavender (EDTA
Pink, white, royal blue (EDTA)
Gray-Na flouride/potassium oxalate
Dark Blue-( FDP)
I hope this is helpful!
