Color Coding / Formatting in Xpressos

Formatting

If the Xpresso operator name is surrounded by brackets "{}" is to represent they are constants.
If the Xpresso operator name is surrounded by square brackets "[]" is to represent they are a group of operators used for a single function. They may respect the BLURPLE color code, or they may not. Used mainly to improve readibility.

WHITE : #E6E6E6 This is used for Data Blocks, they just store data triggered by other functions.
PURPLE : #A445CC This is used mainly for the menu node, but it can also be for the main processing operators.
YELLOW WITH YELLOW BORDERS : #FFE500 This is for notes left in Xpresso to explain how everything works, they can be confused for error nodes so be sure it says "NOTE" and it HAS a yellow border.
BLURPLE : #8A8AE6 This is for a group of operators needed for a specific function, they shouldn't need to be modified to introduce a new set. You can open them by double clicking with SHIFT held.

Some color codes that you can use for grouping nodes used for one single function.
