#0

#0 is often used as a reference to the topic, on forums where posts in thread are numbered.
The first posts has #0, the first reply has #1 and so on.
Many forums have a "quote" function, where the actual text you want to quote on is shown.
If this is not the case, #number is used to refer to a specific post.

In some rare cases, when a posts is deleted, the numbering will automatically try to fix the order, which can be messy if a user has made a reference to a post that is deleted, and thus refering to something that doesn't make any sense.

- #0 speaks the truth!
- I agree on what #3 said, but #8 is all wrong.

#00ffff

*Aight, this is gonna be long* #00ffff is the hex code for the(kinda confusing) colo(u)r cyan. Cyan is a bright shade of blue that is commonly described as "The Best Colo(u)r". Personally, cyan is my second favo(u)rite colo(u)r, after sky blue.

This colo(u)r is slightly related to lime green(#0000ff), which gets the bronze medal for my favo(u)rite colo(u)r list. Cyan is also the first part of a type of poison, known as cyanide. Cyanide is what many people believe as what Adolf Hitler used to commit suicide, after he had lost all hope in WWII.

The hex code is obviously #00ffff, but why? Each hex code has 6 digits. The digits are the first 6 letters of the alphabet, and all of the number from 0 to 9. RGB has three digits. It is also an acronym. R stands for red, G stands for green and B stands for blue. Since RGB is 3 digits, the "deepness" of the colo(u)r is shown with just two digits each. Since blue put with green is cyan, the hex code is #00ffff. I hope you have learnt something today.

#00ffff is the hex code for my second favo(u)rite colo(u)r, cyan.
