For example, you want to set 40% alpha transparence to #000000 (black color), you need to add 66 like this #66000000.
Binary UUIDs are much more efficient in space and lookups compared to VARCHAR or CHAR UUIDs. To better exmplain how they work I have a few examples of raw sql and how that translates in a programming language like Ruby using the UUID tools module. All examples will reference the following database table and schema.
Table name: users
id :uuid(16)
first_name :string(255)
last_name :string(255)

If you prefer to watch video tutorials with live-coding, then check out this series I recorded with the same contents as in this article: Egghead.io - Introduction to Reactive Programming.
