The sun is brutal, here. Anything outdoors fades in short order.
For things like the house, it's no big deal -- the colors chosen
"fade well" (unlike some stronger color choices) and the whole
building fades at the same time (no "shadow lines").
But, smaller things with more vibrant colors really wash out quickly.
E.g., all of the knobs (is that the right word?) on our hose bibbs
have virtually no color left to them. If they'd HAD none to start
with, it wouldn't be noticeable. But, as it is, they just have
ghostly suggestions of past glory!
Are certain (types of) paints better at holding their color?
For small stuff, acrylic paints come in spray cans.
Reputable companies test their products for outdoor weather-ability.
I've seem devices like a Weather-Ometer for accelerated testing and have
also seen test panels exposed to weather for years.
Lots of products, like your hose bibs are probably not tested for
weather-ability and plastics can fail more rapidly than the pigment they
contain. These things are not painted but the pigment is dispersed in
the plastic but weathered surface may frost over from the polymer
degrading and hid the color.
Could be painted metal. If so, I would look for an acrylic paint for
outdoor use. Fading of color depends on light stability of the color.
Pigments from metal oxides or salts generally hold up better than colors
from dyes but cans would probably not tell you what is in it. You could
probably look up stability for different colors. Black that comes from
carbon and white from titanium dioxide should hold up best. Iron oxide
reds probably so too.
(sigh) And I was *at* The Paint Store just yesterday! Crap. Too many
"issues" to keep track of with too little grey matter...
"Knobs" in question *were* red. But, who knows what the pigment
source was (when you buy a bibb, they're probably assuming you're not
interested in where the color originated!)
OTOH, there really aren't many color choices available. Hence the desire
to learn what to look for in a *chosen* paint...
Most of them are powder coated, likely with an epoxy thermosetting
(the cheapest type and not really recommended for outdoor use) powder
that fades quickly and weathers pootly. Acrylic and Flouropolimer
thermosetting are the best thermosetting - and Nylon is the most
The commercially available knobs are generally red (for hot water)
blue (for cold water) , yellow (for natural gas or non-potable water)
and Green (potable water-common for external irrigation etc)

Yes, and they also tend not to be very interchangeable. E.g.,
gas valves tend to be "stops"; you don't turn the gas on "just
a little". So, ball valves. OTOH, if you expect the valve

have a look!]
My first thought was just to buy "replacement" *knobs* of
particular colors. But, different valve stems, manufacturers,
E.g., I selected large "knobs" as small knobs seem to be harder for
aging hands to grasp (it's unlikely that I will be getting YOUNGER!).
As well as some other mechanical constraints dictated by the locations
of each, mounting style, etc.
Rather than add all those criteria to a wish list -- with ZERO
chance of finding "assorted colors" AND those constraints,
I simply found something that addresses the mechanical
constraints (I can *change* a COLOR, but not a casting!).
Now I'm stuck with that color changing aspect of the problem...

Spray paint in general is junk. It needs a
lot of fillers to make it spray well. But pigments
can also vary. Some reds and blues seem to
be worse than other colors. But even if you
can research all that, you might not be able
to find out what specific pigments are in a
I don't know what a hose bib is, but if it were
me I'd try getting some good quality oil paints,
like the "safety" or "international" commercial
paints, then perhaps combine those with patterns:
white with polka dots of orange, white with
orange stripes, orange with polka dots of white, etc.
That way you need less colors and can make them
more distinctive. You can also reduce uncertainty:
If you have blue with red stripes but not blue with
orange stripes then you don't have to see the colors
as clearly to identify them.
You'd not be able to resolve that level of detail at
any distance. Recall, it's not a large, flat surface
that you are "marking"!
Blue, Red, Yellow, Green -- assuming all are VIBRANT
colors and REMAIN vibrant -- would be sufficient.
Don't need the big box of Crayola's, here!
(Black would be unambiguous -- as wold white -- but may
not stand out being that small at a distance)
Do you need the colopr to determine "which" hose bibb it is? or just
to locate it?
Can't remember where on the house it is??
Mine is a foot from the edge of the deck and a foot from the basement

There are 4 hose bibs scattered around the yard -- in addition to the
three that are part of the house.
The four that are scattered around the yard are *individually*
controlled by solenoids -- fed from the irrigation water supply.
The ones on the house are fed from the DOMESTIC water supply.
i.e., DON'T want to use that water for "non-domestic" uses...

Because of the way the bibbs are controled by solenoids, you
can attach a hose to one, run it across the yard to a particular
place (e.g., a new planting), set the "knob" to the desired
flow rate (i.e., ON!) and leave it there indefinitely... without
using ANY water!
You can then tell the irrigation system to treat that "bibb"
as a particular "water load" and activate it based on whatever
criteria is appropriate (e.g., if it hasn't rained in a week,
let it run for 15 minutes AT THE CURRENT MANUAL BIBBB SETTING!)
You can similarly run a hose to a bibb, then carry the end across
the yard to start filling a hot tub. Instead of having the water
running while you drag it across the yard (we live in the desert),
you'd undoubtedly drag the hose across the yard. Then, walk BACK
to the hose bibb to turn it on -- hoping you'd got the flow rate
set properly (cuz the end of the hose is now ~30-50 feet away,
tucked into a barrel/jacuzzi/etc.)
In *my* case, you can command the water "on" and the system
will note your position in the yard and assume you mean "the
hose bibb that I am standing next to, at the present time".
The solenoid valve is then engaged and you can now set the flow
rate by MANUALLY adjusting the "knob" on the hose bibb while observing
the rate water exits the hose (in your hand!). Then, without
altering the setting of that "valve", you can command the water
*off* (solenoid). Now, you can drag the hose across the
yard (not wasting a drop) and drop it into the barrel, etc.
Some time later, you can look across the yard, see that the
hose bibb you used (evident by tracing the hose back to its
source -- in case you've already forgotten!) and identify
the COLOR of the knob/handle.
"Water On" is likely ambiguous -- or, even WRONG (e.g., you
might be standing next to some OTHER bibb that you actually
DON'T want to turn on!). So, "Red Water On" gets you the
desired action (assuming the knob on the hose bibb off in the
distance was, in fact, red!)
Or, you could remember that the bibbs are roughly NE, NW, SE
and SW. Of course, that wouldn't help someone who didn't
already have that knowledge in their head!
Or, I could paint big digits on the walls nearby each bibb
so you can identify them numerically (NOT!)

If you had to schlep your (wheelchair bound) butt across the yard

to just "command" it on! (or off)

"Quality of workmanship". It's not a nice *flat* surface but, rather,
has all sorts of countours, "insides", "outsides", etc. I think a
brushed job would show lots of brushmarks and pooled paint/drip
Spraying would allow a more uniform application: hang it from a coat hanger
and hit it *lightly* from all sides. Lather, rinse, repeat.
