h = hex (i'll add x for hex as well)

a = alternative
t = transparency factor

s = gray value

p = spotcolor percentage
e = spotcolorname

<name 1> = duotone 1
<name 2> = duotone 2

that's about it

I wikified that:

But how's it possible that h and s have two meanings? Does HSB mode work
at all? (Didn't try.)

hsv should work (it's the 'v' that triggers the meaning)

What means "alternative"? (So far I only know that it should be 1 for
transparency.)
