I've had good luck with Home Depot in matching the color. Take the cabinet
in and heave them scan it and the can mix up a sample jar of Latex (yeah,
sorry - latex) for you for just couple of bucks.
Then get the Preval paint sprayer kit (If you don't have an paint gun). I
like the Preval as it is made for small spray paint jobs. You could do the
whole cabinet if you wanted to.

Every so often I get repeat requests for the formulas of the paints that I
use on boat anchor cabinets.
Here are the formulas from Sherwin-Williams of the cabinet colors that I
have had matched to date. Note that these are for 1 quart unless otherwise
noted.
Also, all but 2 of thse I now have in acryllic (which dries MUCH harder than
normal enamel) and all are water-based except for the Johnson maroon which
also has an oil base formula. The 2 that I have not yet acquired in
acryllic are for latex enamel but acryllic is available and your local
Sherwin-Williams store (and any other paint store that has paint mixing
capabilities) can provide acryllic paint using the same color formulation.
I always prime the cabinet before painting and what I use is the "el cheapo"
primer from WalMart which costs
97 cents for a 10 ounce spray can. It is ColorPlace Gray Primer #20010.
For a medium "crinkle" I overspray the primer with Rustoleum "Stone
Creations". This comes in several colors but I have found that the gray
color seems to work best. You have to hold the can between 14 inches and 18
inches away from the surface and spray in very short "bursts" while moving
the can slightly. It akes a little bit of practice (try spraying on a piece
of
cardboard) to "get the hang of it".
A paint that generally furnishes a light wrinkle is Krylon 3370 Jet Black.
However, you need to apply heat to get it to really wrinkle correctly and
then it may not work correctly every time. Therefore, I usually use the
Stone Creations paint.
After the "crinkle" or "wrinkle" pain has dried you then need to overspray
with the correct color.
Now the paints that I am giving the formulas for require some type of spray
paint rig (unless your paint store is one of the relatively few that can
load spray cans). There are all sorts of possible solutions ranging from
simple arrays that consist of a can that may be pressurized using a bicycle
pump all the way to compressors and "real" paint guns. I use a compressor
and paint gun but for occasional use those cans that can be pressurized do
work (they are available from Harbor Freight and many paint stores).
The formulas:

"Off the Shelf" or "standard formula paints for those who do not want to get
their paints specially mixed.
Collins:
KWM-1
Standard formula paint ASA 61 Gray. This is a "standard" industry formula
and should be available at just about any paint store. ASA 61 is an "exact"
color match to the KWM-1.
S-Line cabinets (not trim ring). Real close (but not a cigar) "off the
shelf" is Rustoleum 1982 Winter Gray.
RME
Cabinets from the late 1930s to the 1950s. Really close "off the shelf" is
Krylon 1608 Smoke Gray.
I do not have any other paint "matched" at the present time. The formulas
are presented for those who are wanting to repaint their equipment the
original color.
Most of the radio manufacturers did NOT prime their cabinets before
painting. I do NOT recommend painting over the original paint because this
will often cause the original paint to "flake off". You need to completely
strip the original paint (sanding where
necessary) and then prime the cabinet. Then paint it with the desired
color.
