I've never used the system 7.5 label colour wheel, but have the 7.1
version. It returns 2 byte unsigned integers. Anyway, to convert
these to hex values follow this algorithm where val is the value to
be converted.
Note that the hex digits are 0..9,a,b,c,d,e,f where a..f represent
10..15
While val > 0
do
x = power of 16 <= val (so that val >= 16^x)
y = a value such that y*(16^x) <= val
output y to RHS of current output
Note that if a power of 16 is missed then output 0.
val = val - y*(16^x)
done
eg. 31706 in integer
val = 31706
x = 3
y = 7 (since 7*(16^3) <= val; 28672 <= 31706)
output = 7
val = 3034
x = 2
y = 11
output = 7b
val = 218
x = 1
y = 13
output = 7bd
val = 10
x = 0
y = 10
output = 7bda
====
So now 7*16^3 + 11*16^2 + 13*16^1 + 10*16^0 = 31706
I hope that helps,
