They are.  They're just 12-bit values rather than 24-bit, so you have to
change $N to 0xNN.  For example, "Orange" changes from $0F60 to 0xff6600.

The colors you came up with are very similar, though there are some
differences.  There is some question over whether these values are "out
of gamut" for NTSC, meaning that they're valid if you're pretending to
be an RGB monitor but not quite right if you're trying to look the way
an Apple II does on a television.

The following is based on the actual technical properties of the
(pre-IIgs) Apple's video out circuits, and of the NTSC norm from the
late 1950s. It's recommended to set your PC monitor's Color temperature
to 6500K, like the NTSC norm specifies.

To get any fancier you'd have to convert the Apple's display phase
angles to real XYZ values according to the ISO base colorspace standard
and then find a transformation from XYZ to your monitor, using its xy
values for red, green, blue, and white, which are probably documented
somewhere. Can be done, but it's a lot of work.

LO-RES:
0 #000000
1 #e31e60
2 #604ebd
3 #ff44fd
4 #00a360
5 #9c9c9c
6 #14cffd
7 #d0c3ff
8 #607203
9 #ff6a3c
a #9c9c9c (yes it is the same as #5!)
b #ffa0d0
c #14f53c
d #d0dd8d
e #72ffd0
f #ffffff

HI-RES:
0 #000000
1 #14f53c
2 #ff44fd
3 #ffffff
4 #000000
5 #ff6a3c
6 #14cffd
5 #ffffff
