Hexing is a fun thing to do after you know how to do it. You can Hex up to 6 letters/symbos/numbers and you work backwards you will see what i mean when i show you the codes. There are 4 Address codes(the first 8 numbers in the code)There also shown on the hex chart below.

I am going to show you how 2 hex my name ADOGG in red each letter or number like the A in ADOGG has 2 numbers like

A=41
D=44
O=4F
G=47
G=47
Heres how to hex 1 color
Now to the hexing part the code for the color red is 32635c and you put that right after you put in. The code for the first number/letter/symbol in your
name in this case my first letter is A and the code for A is 41 so i put 41 right before the red color code (32635c) so that the first line
ends up looking like this.
4132635c
Then you add in your other letters/numbers/symbols in for the secound line and remember you put the codes in backwards like this... and leave out A/41
in this case or the first letter in ur name
47474F44
Then add your address codes in so it will look like this
207c2d70-4132635c
207c2d74-47474f44
Now heres how to hex 2 colors
im going to hex ADOGG again remember the codes for ADOGG
A=41
D=44
O=4F
G=47
G=47
this time im going 2 use 2 colors red(32635c) and green(34635c) So the name would be ADOGG
You are gonna need 3 address codes now for the first line just do the same as u would do for one color it would look like this
4132635c
Then this time put the color code(34635c) in first and then put the next letter in in this case its D=44 so it would end up like this.
34635c44
Then for the last line just put in the codes backwards but in my case i add zeros in the first 2 numbers so that it looks lik this.
0047474f
Then just add the address codes in so it looks like this.
207c2d70-4132635c
207c2d74-34635c44
