Hmmm... where to start ...
Numbers is numbers. In base 16 (hexadecimal) or base 10
(good ol' human-friendly decimal) numbers is numbers.
What they mean depends upon context. When you are talking
about colors, numbers frequently refer to mixing levels of '
Red, Green & Blue -- thus 000000 is 00 Red, 00 Green, 00 Blue;
which is the absence of all color: hence black.
When discussing computer CPUs, numbers frequently represent
instructions such as MUL, ADD, MOV -- each instruction has
a numeric value, and the numeric value representing a MOV
instruction is likely to be different for a Pentium (Wintel)
than it is for a Dragonball (Palm).
But bear in mind that the -only- thing that computers understand
is numbers. These characters I am typing are -also- represented
by numbers. The letter 'A' for instance has the numeric value
of 65 (... in decimal, $41 in hex).
Towards the end of your question you seem to imply that what
you are after is information on how to program the Palm. That
is a completely different question that what you started out
asking ... and I wish I could be certain that that is what you
really want to know ... generally you don't program in the
machine language (i.e. numbers), so give your initial question
I am still not certain what information you are really after.
Hexidecimal, display color coding, programming ... your questions
are really all over the place ... perhaps because you are trying
to interpret what you think you know too much into the questions
you are asking.
Please, describe your situation and what you want to do. Do you
have a program and you want to decode it's data files? Do you
want to use display codes to display underlined or bold characters?
Do you want to learn how to write programs? Or what?
