Sadly, in AutoHotkey scripts you can’t just demand “LIME” or “GENTLY BURNT ORANGE”. The computer will spit out an error message if you try. It requires a color ID in hexadecimal BGR (Blue, Green, Red) format.
If you’re wondering what the hell that is, you’re not alone.
The simple answer? It’s an 8 digit code assigned to each color. Look them up on Google if you want to preserve your mental health.

The Complicated Answer
I just relearned how to count, damn it. That’s how complicated this is.
You see, Color ID’s are made up of a fixed prefix and numbers that represent a combination of blue, green and red.
The amount of those colors can be anywhere between 0 and 255. Here starts the problem of counting. How do you tell the computer to use the max green value (255) if you can only use a 2 digit number?
You use a different counting system by adding letters A-F. That’s how.
It’s Base-16 because you’re counting by combining 16 characters: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, a, b, c, d, e, f.
If you’re only manipulating one color while the others are at 0, all you really need to know is that lower values are darker than higher ones.
When you start combining colors, the same normal color rules apply. To make yellow, you jack up the red and green values, so the BGR will read 0x00ffff. Blue and red makes purple, so 0xff00ff.
The oddest thing to get used to is white being the max value of blue, green and red combined, 0xffffff. Just remember that the higher the value, the more they cancel each other out until they reach nothing. White.
