Thanks for you're contribution, it's a great start

However, you may need to change the naming conventions of you're blocks. (Example HexColorCode should be hexColorCode) as followed by the lowerCamelCase

@Taifun

What does lowerCamelCase mean?

lowerCamelCase (part of CamelCase) is a naming convention in which a name is formed of multiple words that are joined together as a single word with the first letter of each of the multiple words (except the first one) capitalized within the new word that forms the name.
