Ah, the Barclay camouflage experiment. I started skinning one of the Buffalo schemes, but put it aside last fall. Maybe I'll dust it off and finish it.

that looks cool as hell. but what's the purpose of a camouflage like that?

Looks like a VW Bus from the 1960's http://forums.ubi.com/images/smilies/16x16_smiley-very-happy.gif

I'd guess the idea was the same as the dazzle pattern on some WWI warships.

You don't camoflage an object merely by painting it in a back ground colour; but attempt to decieve the eye by breaking up it's out line shape; which interferes with the brain's object recongnition..

Think of the typical commando's face: He doesn't just paint it black; that would defeat the purpose; but paints it in an irregular stipe pattern so that at a glance; it doesn't register as a face.

What DmdSeeker eludes to is really a very important aspect in camouflage that is used to this day. Using hunting camouflage as an example, makers discovered that a tight consistent pattern simply looked like a "human" dressed in camouflage....The human shape retained. However, by adding large patches of a single color, almost as though nothing was there then the form begins to get lost. You can never perfectly match background, yet camouflage just a small part of actually concealing something....

Anywho, before I sound more of dweeb then I do.....You have to look at these patterns from a distance with the background they were meant to hide in to appreciate them.

Visual Camouflage is all about disguising:

Movement
Shadow
Shape
Shine
Silhouette
Spacing
Surface

In addition, Sound can attract the eye, and in close combat, Smell can warn the enemy of an unexpected presence.

You can break it up into 3 basic problems;

i) Preventing Suspicion. If the enemy doesn't suspect you, he is unlikely to look for you.

ii) Preventing Detection. If the enemy can't see you then he can't respond effectively, even if he expects you.

ii) Preventing Identification. If the enemy can't identify you correctly he cannot respond correctly, even if he has detected you.

This sort of camouflage is intended to attack problems (ii) and (iii). Since peripheral vision is essentially monochrome, what really matters is not the colour of an object, but rather its luminosity at about 498 nanometres.

http://en.wikipedia.org/wiki/Rod_cell

Since the human eye has limited resolution, at long ranges, multicoloured objects are perceived as being monochrome objects of the average colour of their components. So if you have an object painted in red and yellow stripes for example, at long ranges it will appear orange.

This means that at long ranges quite strange colour combinations can be extremely effective, especially in low light conditions:

http://en.wikipedia.org/wiki/Purkinje_effect

At closer ranges it's very unlikely that clever colour schemes will prevent the detection of aeroplanes since their size and movement are almost bound to give them away. Therefore, the primary task of camouflage becomes misidentification.

For this purpose the goal is to disguise the shape of the aeroplane. Since we detect shape by looking for "edges" (areas which exhibit rapid changes in colour or luminosity), adding artificial edges to an object can be quite disruptive to our ability to to work out what it is, especially if it is presented against an anisotropic background. Disruptive camouflage with a mean luminosity at ~ 500 nm close to that of its intended background can therefore be extremely effective in disguising aeroplanes seen from above.

Of course since the sky during the day tends to present a largely isotropic background which is highly luminous, it generally pays to adopt a different strategy, and so the undersides of aeroplanes tend to be painted in a monochrome scheme with a carefully selected colour.

All of this technology can of course be greatly assisted by avoidance of obvious formation flying, and the adoption of a matt finish.

Viper 2005, very good description and writing skills. I must ask, did you write this or cut and paste it? If you wrote it good job.

thanks a lot everyone. I know about the general purpose of camouflage but I've just never seen a pattern like the one in this thread so I was wondering what sort of surroundings it's meant for.

anyway, thanks a lot http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif

Here's another one. This is a black/white application over common olive drab for visual sighting tests.
