r = red channel
g = green channel
b = blue channel

c = cyan channel
m = magenta channel
y = yellow channel
k = black channel

h = hue or hexadecimal
s = saturation
v = value (or so)

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
