** edited to CMYKW **
**** EDITED AGAIN TO FULL SPECTRUM
Spraypaint because somebody said that
CMYKW sounded like they were cleaning
their nose out ****
********* punk critics. Changed to Full-
Visible Light spectrum spraypaint
********
Spray paint comes in all different colors,
but
I have seen many many cans used
and
wasted because they were used once for
some project and then stored on some
obscure shelf behind the laquer, never to
be used a-g-a-i-n. What the world
needs
is and multi-color painting solution...
Introducing: The multi-color painting
solution! (could not come up with any
interesting name)
It can concoct any shade of color by, and
here's the magic (infomercial style), it
comes with 5 individually pressurized
paint contains, yes, you heard right, 5!
When you combine just the right amount
of one or more of these 5 different
paints,
you get EVERY COLOR IMMAGINABLE!
Here's the secret to how this thing works!
There are different dials on the top of the
device that controls how much of each
can
of spray paint is let out when the main
trigger is pressed. You want red? simple
as that [psssst.], orange? just turn the
dial
to your desired shade or orange and
[pssst. pssssst.], wow, just look at that,
just like magic. Purples, teals, blacks,
greys, pinks, every shade of green, you
name it, this here can do it!
5 individual containers, containing
CMYKW, combine to
make it all happen ladies and gentlemen.
Now for those who think that the color
will
become inconsistant because of
individual
can pressure, you need not worry,
because
the device adjusts for the different
pressures, assuring you color accuracy
that can't be beat.
These 5 containers can be individually
bought, just like ink cartridges, but at
your hardware paint department. This
way, you don't have a cupboard of old
spraypaints that who knows how old they
are, you have one, spray can, that can do
ANY COLOR YOU WANT.
you can borrow this if you like.

not bad..... but what happens when one
of the cans runs out ? (+) for thinking
behind idea. |
|
| |
RBG are additive colours, you're going to need a subtractive (CMYK) mixture. |
|
| |
[tom]'s right, coloured inks work differently to coloured lights so you would need a CMYK can. I don't think you'd need the white... Bun though for the basic idea [+] |
|
| |
+ Yeah, I do have a bunch of old cans of paint. It's a nice idea, even if it wouldn't work all the time. |
|
| |
Yes, RGB, because you don't always spray
on white, therefore your white has to be
supplanted by a sprayer. 5 cans, RGB,
black and white. |
|
| |
And I mentioned, that you can buy
replacement cans at the hardware store,
like you do ink cartridges at officemax. |
|
| |
OK, if you're going to use RGB, what combination of red, green and blue paint are you going to use to get yellow? |
|
| |
CMYK (where K in this case, is white) allows you to reproduce all the colours in paint (subtractive colour), no matter what colour surface you are painting onto, and using only 4 separate inks. |
|
| |
Well then i'll use CMYK.. and I thought that
K was black. Atleast that's what I think I
learned... My printer uses CMYK, and the
K is black. |
|
| |
You'll need CMYKW, the W being white
because if you want to put a neon pink on
a black poster-board, you can't do it
without a mix of white. CMYK is for only
white printing paper. |
|
| |
Looks like it's redundant [twitch] - do
the right thing. |
|
| |
I disagree about being redundant. the 4-in-1 can has a separate nozzle for each compartment, which wouldn't really work for this idea. The in-can mixing of the colors is essential. |
|
| |
Totally un-redundant! 4-in-1 can? it
would be almost impossible to get the
color accuracy as my idea proposes, the
user doesn't even have to know what
colors are being mixed! |
|
| |
The problem with this is the same as with colour printers, when one colour runs out you need to change the whole cartridge (except more expensive printers). |
|
| |
the reason there are so many colours is the same as Pantone colours in printing, you can't make some colours from CMYK, gold for example. |
|
| |
isnt' gold just a yellow color? it's the
specularity that makes the difference i
thought. |
|
| |
It's not RYB either. See above.
However, whatever colours you combine, I don't think you could ever accurately reproduce all colours that are available by purpose designed paints. You could get close, but not perfect. |
|
| |
How close could you come though? If you
were painting a whole wall and wanted a
specific color, you would just go to the
store and have them mix you the color,
but this is not for volume painting, this is
for touch ups, artwork, misc. projects. |
|
| |
[marked-for-deletion] redundant. how close to another idea for redundancy is a fine line but I've called it. |
|
| |
[twitch], I think it's because certain compounds only absorb certain colours of light in specific bands. Those bands cannot be accurately reproduced using a combination of other compounds. |
|
| |
[po], what's so redundant about it? there
are many ideas of having 4-in-1 cans, and
even if my idea uses this, which is
redundant, doesn't mean that it is the total
of my idea. It is the mixing mechanism
which also compensates for differing can
pressures which is the real magic. As well
as the purely mechanical genius of a color
selector. THIS implementation, i have not
seen on HB, or anywhere. |
|
| |
//many ideas of having 4-in-1 cans// where? |
|
| |
Disagree with your [mfd], [po] dear. The 4-in-1 can you cite doesn't actually put forward the idea of mixing them to get the whole gamut. |
|
| |
As I understand it, CMYK will allow you to get almost any hue, but maybe not to full saturation - which is why the really expensive photo printers have more than 4 ink cartridges. Most inkjet printers will give you a chart, showing just what colours in the human-visible spectrum they will reach. |
|
| |
Bun anyway - I think this is a great idea. It would make shading and graduating interesting - perhaps they could be automated processes! |
|
| |
I know what you're saying [moomie] but I really think paint mixing to this degree would be impossible in a spray can. can you imagine the clogging? |
|
| |
No, i can't imagine the clogging, because
those small things can be simply
mitigated. If i had to solve every little
problem within my idea that would take
pages. |
|
| |
I liked the old title. CMYKW sounds like clearing my sinuses. Actually that is more of a CMYKWUUUUH. |
|
| |
just because you can't imagine it, doesn't mean the problem does not exist. |
|
| |
I should have said, I can't imagine clogging
being a large problem. I've worked with
spraying systems and cleaning them is not
a difficult task, for those who know how. |
|
| |
Yes, best change the name again [Twitch], before your idea loses credibility. |
|
| |
SOMEBODY's going to beat me over the
head over some semi-relevant detail
again, I KNOW IT, rather than focus on the
concept. DON"T BE J. |
|
| |
When you finally come to use this spray can, [twitch], [Ian Tindale] will be the one who walks past just as you're cleaning up and says 'You missed a bit!'. |
|
| |
Strictly speaking of course, white is not a colour in the spectrum. |
|
| |
It still claims to produce any colour imaginable but there is yet to be any explanation on how it will produce gold, or silver, or some other shine finished colour. Perhaps a matte/shine cartridge is in order to produce these effects. |
|
| |
Would mean a change of name though... |
|
| |
OK, so you start with a base and add the appropriate pigments. You've now got your color. |
|
| |
Add an extra can to determine finish quality. Matte? Satin? Semigloss? Gloss? |
|
| |
How about metallics? Flake size? Flake material? |
|
| |
How about irridescents? Flake size? Flake thickness? Flake material? |
|
| |
How about textured paints? |
|
| |
[Freefall], then you can use the 28 cans-
in-1 sprayer. It's perfect for you. Gold is
not just a color, it contains a specularity
value, like silver. It's the shimmer, not the
color that identifies gold. |
|
| |
Wouldn't it be simpler to have transparent
LCD glasses? With some inertial
navigation, GPS and suitable software, you
could map whatever colour scheme you
liked onto the world around you. You
could even have animated or furry virtual
paints. |
|
| |
Resolution would not need to be high -
the brain doesn't map colour very closely. |
|
| |
[admin: po, I see where you're coming from with the MFD, but I'm not deleting the post - I think it's different enough in construction, use, and result.] |
|
| |
Not just different in construction, but the
whole concept! The simplicity of turning a
dial to a desired color, and another dial for
brighness/darkness... I have not seen
these concepts anywhere on HB. |
