Hello,

Regarding color codes and converting between them, are ARGB & RGBA identical except for the alpha transparency value position? Are they interchangeable?

Also, what is the "0x" prefix which is so commonly included?

Example (from the 2nd link included below):

"ARGB integer value (0xAARRGGBB) or HTML color name ("Red")."

I understand RGB & Hex and how to convert back and forth but I've not used the alpha parameter previously. I've read that it's a hex value which defines transparency but that's about it.

Specifically, I'm trying to build a GUI with multiple colors of buttons using AutoHotkey (AHK) and an AHK utility found here:

This is representing hexadecimal in the C programming language.

The # represents hexadecimal in HTML pages.

See https://en.wikipedia.org/wiki/Hexadecimal#Using_0.E2.80.939_and_A.E2.80.93F and the section below.

See https://en.wikipedia.org/wiki/RGBA_color_space

They are the same.  It is just how they are stored and used.  The article also talks about 0x and # again as well.
