Red is one of the nicest colors to tell this apart!

The red color is great for finding the pieces of the repair set, while you are taking a phone apart. It is easy to see that isn't a piece of the phone you accidently picked up. The 115 pieces is one of the most complete sets I've ever seen for a micro screw driver set. This set is extremely affordable and it is so simple to find exactly what size you need. There is so many pieces I don't know if you would ever need another set besides this. it appears to have every different kind that would allow you to work on iPhones to Android to Windows phones.
