If it's percentage, just multiply by 100/255.
Another possibility is that Frame is using hexadecimal, base 16.
If so, right hand digits are:
0 to 9 plus
a = 10
b = 11
c = 12
d = 13
e = 14
f = 15
and left digits are those values times 16 so
hex dec
10 16
20 32
... and so on
f0 240
So, for example,
To turn decimal 35 to hex, you notice that it is 32 + 3 so you can
write it as hex 23.
To turn decimal 173 into hex, you divide by 16 and get 10 with remainder
13, so the hex value is "ad".
That might be written "AD". Hex can be done either way. It might also
include an indicator that it a hex number and be written "ADh" or
"0xAD".
