IIRC, it's something like 1 in 15 (among men).  What's amazing
is how ignorant many people are of this fact -- esp folks who
ADVOCATE the use of color in indicators!

(Low light conditions also wash out color sensitivity in most
people)

Depends on what you mean by "Tone deaf".  Many people can't carry
a tune in a bucket -- yet can synthesize and recognize *difference*
in tone.  Most musicians *don't* have "perfect" pitch but, instead,
rely on "relative pitch" (recalling the ratios of frequencies
though requiring "calibration" to some recently heard "reference
tone")

Modulate (gate) the sound to that it manifests as short and long
"sounds" and "silences".  Taking care to include a long and a short
in each "report" to serve as a reference for the user.  Of course,
you also have to avoid the extremes in frequency range as they
tend to alter with age (stick to the sweet spot -- speech -- in
the audio band).

The same applies to blinking indicators -- regardless of whether
they are multicolor or monochromatic.

Trying to address accessibility issues involves quite a bit more.

E.g., dealing with a *deaf* user will leave you stumped!  Hearing
users can have their attention drawn to <something> with a percussive
noise.  When the party you're interested in can't perceive this,
you have to come up with other ways to get them to *notice* the
flashing light, etc.

Think about how your product is normally used, interacted with,
etc. and see how you can inject an "asynchronous notification"
therein.

Personally I think it's best to use code. Beeeeeep - good. Bip .. bip ..
bip .. bip - sumpthin's wrong. No sound - it ain't working. I wish that
was the same for optical displays.

A client goes a step further. They are using morse code to announce the
status of a system. I could turn it on, go down the hallway and into the
kitchen to get a glass of water and still hear whether it started up
alright and what firmware version is in it.

Don't forget a significant number of people are deaf
and/or have tinnitus.  Depending on the for their
deafness takes, they might not even hear some or all
of the noises, let alone distinguish them.

And most people become quite adept at ignoring sounds
that they hear too often, particularly when they are
concentrating on something else.

Whether or not any of that matters largely depends on
the consequences of missing some of the sounds.

If it's just for bench equipment, could you keep a red or green filter
(colored cellophane or whatever) handy?  Then just hold the filter in
front of the LED to check the LED color.  Red cellophane will make a
green LED look dim while not significantly decreasing the apparent
brightness of a red LED, and vice versa.

Of course, some colored film or 'gels' would be much cheaper and just as 
handy.

Guessing you want glasses that null the offending colors -- purple absorbs 
green, making green look black (in the most common red-green 
colorblindness).  Presumably, cyan would also work (complement of red, 
making red look black instead -- so don't mix up your cyan and purple 
'shades!).  It follows, you want the complementary color for whichever 
type of colorblindness you have; the other kinds, being rarer, presumably 
have rather expensive glasses for them, making the cheap solution all the 
more handy.

That is not too bad. Many people can't tell left from right.

Toggle LEDs with different duty cycle. It is easy to distinguish 2 - 3 
basic flash patterns.

I can do you one better.  One time while driving with my girlfriend (at 
the time), she attempted to provide directions:
[points to the right] "go yellow!"
"I mean, left!"
"I mean, RIGHT!"

I didn't let her live that one down...

Speaking of cars, most have a diagnostic mode (enabled by jumpering the 
diagnostic plug, or doing a magical dance, e.g., toggling ignition five 
times) which blinks out diagnostic information.  Newer cars (i.e., since 
the 90s) of course have various numeric, alphanumeric or graphical 
displays in them, but older ones often used the "check engine" light.  My 
'95 Toyota, for example, blinks out unary sequences:
- a blink is something like 0.2 seconds ON, 0.8 seconds OFF
- a series of blinks in a row is a digit (i.e., count the pulses, 1 
through 9 -- not BCD, but UCD -- unary coded decimal)
- An extra second between blinks indicates the second digit (thus 
expressing numbers 11-99 except whole multiples of 10, since there's no 
zero)
- Two seconds delay indicates another pair of digits (if multiple error 
codes are present)
- Five seconds delay and the sequence repeats

I probably have the exact times wrong, but the grouped pattern is clear 
and pretty handy.  Unary gets tiresome after a while, so if you need 
status faster than it blinks, you'll need a different method.

Strange, I would code "0" as ten pulses.

Yes, that would be logical.  Didn't matter in the present case, as codes 
were pairs of digits, each enumerating a condition, not together as an 
actual numerical quantity.  As I recall, the first digit was subsystem 
(ECU, ABS, etc..), second identifies what (oxygen sensor, ignition, 
etc..).  If one system had more than 9 error codes, dunno... they might've 
just keep blinking it?  Of course, most systems had only a few codes each, 
so most of the numbers that could be expressed weren't needed.

When swapping to driving on the wrong side of the road
on holiday, to our surprise both I and my wife confused
"go left" and "go right" in the same way.

Problem was removed by saying "go your way" and go my way"

About 1/3 of the world's population drives on the
correct side, in about 1/3 of the world's countries,
if this is top be believed:
<http://www.worldstandards.eu/driving%20on%20the%20left.htm#leftdriving>

Of course in some of those countries, particularly
large countries, there is only a "marked bias" towards
driving on the left :)

Don't know how it works at the border between Hong Kong
and China :)

In some of those places it is more in the towns/cities as anywhere else
you are lucky to find what western countries call roads..

As an obvious an easy to implement solution, why not go to yellow/blue
LEDs?  Almost anyone except the very rare individuals with total color
blindness, will be able to distinguish those, including almost all
cases of partial color blindness.  Yes, those are relatively expensive
(about twice the cost of red/green bi-color LEDs), but would likely be
a near plug-in solution.

In the case of audio, mix different frequencies with different pulse
rates.  IOW, BeepBeepBeep vs. Boop...Boop...Boop vs. Tic..Tic..Tic.

While there are people who cannot hear certain frequency bands, that's
usually the result of some sort of trauma or exposure to very loud
noises.  A complete inability to distinguish tones would make them
unable to understand speech as well.

I dunno, but I do remember a collegue of mine confessing he was color blind.
He was the engineer responsible for running a color TV studio...
I have wondered many times how he got away with that..

Maybe it is the sickness of this society to accomodate for every freaking disability
and that way make life more difficult for 99.99 percent of people.

What you want is a color translater, that sees the color (simple to make),
and says RED RED RED  or GREEN GREEN GREEN , or : duck.
whatever.
Design opportunity.

My only problem with all that stuff is: too many menus'.
Gimme a command line.

My putah speaks English.
If I say:
show BBC2 
it pops up BBC2 (if enabled).
I can type it too.

Everyone can tell beep-beep from beep.

My car is programmed to wait until it is going pretty fast, and then sound 
GONG-GONG-GONG (yeah, 3 times and loud) to make the driver jump.  "Oh, no. 
Something serious."  The info display gives details.  "Washer fluid low."
