i've been doing some extensive research into the colour black, my overwhelming conclusion is that black is in fact black.

however, no research would be complete without consulting the collective brain power of the stw masses. i have noticed that even the simplest, most straight forward factual detail can be proved incorrect by an stw expert, so come on, is black black?

surely its just the absence of colour

2/10.
Black isn't a colour, so your research is somewhat flawed

No. It's dark white.

Or dark anything. At a subatomic level its impossible to achieve as those pesky protons get everywhere.

Black is the absence of reflected light, something that is truly black would appear to be a hole in space where no light came from.

How much more black can you get? None. None more black.

There are lots of different shades of black - as you would realise, if you'd ever tried to match up a black skirt, black tights, black shoes, black handbag . . .

As the late Peter Cook once said: "I know where light comes from, but where does black come from?"

Franz Hals supposedly used 27 shades of black in one picture.

There's only one black, all the rest are contaminated blacks with some colour in there.

Interesting point: what colour is used for black on a projector?

White is the new black. Or was that last year?

I appreciate that black is an absence of reflected light and because of this is not considered a colour, but as it's absorbing all the light (colours) in the spectrum, does that mean that technically black objects themselves are the most colourful.............they just don't reflect any color? 😯

As you walk into a room with no light and close the door, what light is being abosorbed so as to produce the non-relfection of any colour. Is it the same answer for shadows. So something black is either absorbing all the colours of the spectrum of available light or there is no available light and it is just black.

(Sits down quickly as brain slowly melts)

Black is a darker shade of grey innit!

How simplistic 🙂

You are right if talking about RGB. Black is black (0,0,0).

However in CMYK there are many different blacks...

I am with Kimbers here - colour is the reflection of light. Black absorbs all light and doesn't reflect any back, therefore it is an absence of colour. (In a true literal sense anyway - as has been said, it is possible to have different blacks - something that is called 'rich black' in the printing trade).

At least that was what I was told at art college, just before they showed me how to whip up £50 logos and charge £500.

Black from a projector = The white on the screen

Exactly!

Once again someone on STW argues black is white 😀

Nothing has a colour, it is just the effect of light on the surface. Imagine looking at a bright red rose at dusk - the colours appear very different than at midday because there isn't the light there to be reflected.

That one is all about relative perception or something - as has been said - the eyes (more specifically the brain) fills in gaps to make things make sense.

Similarly, how does watching a film look like it is moving when it is, in fact, just a series of still frames.

It is the brain - it's dead clever.

Seems to me that a red rose appears red because it absorbs every visible colour except red.

So if red bounces off it and everything else sticks to it then surely it is really every colour [i]except[/i] red? 😉

Also.. something vague to do with magnetic poles and planet alignment... 😀

Graham S - exactly what in a terrible way I was saying - the non-reflected colour (or energy if you will) has to go somewhere.

Not all blacks are created equal.

Luckily I don't deal with colours much but in my project, but as a paint developer it is a problem.

Metamerism is one of your biggest enemies, what is black under one light is not black under another set of lights (e.g. comparing daylight to flourescent tubes).

Therefore black objects are bursting full of colour. If you where to cut it open there would be a rainbow running through it like a stick of rock. 😉

I agree - sort of. Again, objects don't have colour per se, they just reflect light dependant on the properties of the surface of the object against the source light.

Surely realtime life is just a series of stills! 🙄

It is absorbing all the other colours (energy) that are not reflected. Energy is transferred, not created or destroyed so has to be absorbed with the only frequency not being absorbed is reflected and it is that enrgy (colour) is displayed.

(Sits back knowing someone will in fact prove that energy can be both created and destroyed in equal measure)

Yep, time is just an infinite number of individual moments... man...

But it is. The smallest chunk of time that cannot be subdivided (Planck Time) is one second by 10 to the -43.

I admit that's small (there have "only" been 4.3x10 to the power 17 seconds since the big bang) but it's real.

Was being pedantic, if you were to break down time so that you are not measuring 'frames per second', but more like milliseconds (or smaller), then movement could be broken down to a serious of, albeit miniscule, stills.

In the same way that a circle or arc is made up of many tiny straight lines!

Edit: well put Big John more coherent than my wild ramblings but is what I was getting at.
Edit: you to Graham S

Well perhaps to that degree of pedantry. 😉

But the human eye can fill in the blanks at something like 2 or 3 images per second and make them appear to be moving. Persistence of memory I believe that one is called. I was just using it as an example of how the mind can work things out (in a similar way that a projector can't project black but the mind can tell you it is seeing it).

Furthermore, the ability to measure time to a lesser degree doesn't mean that life is a series of 'stills' - it just means that our present ability to measure it has been exhausted.

Surely?

IIRC scientists have recently developed carbon nano tubes which are many times more black than anything previously known. This will lead to more efficient solar panels as more energy will be absorbed rather than reflected. So we have black but not absolute black.

Purple Acki, terrorizer of trim gentlemen in the Northwest of England, (and was so notorious that most people thought he was an urban myth) is of Nigerian decent, and his nickname comes from him being so dark-skinned he looks purple.

So is the answer 'Purple'?
