International Klein Blue is a special shade of blue. It formula registered in 1960 by the French abstractionist Yves Klein.

For Klein, blue color had a special meaning. Klein believed that all other colors cause persistent associations in people, unlike blue, which reminds only of the most abstract things in the world - the sky and the sea.

Klein tried to keep a rich shade of velvet ultramarine, but color disappeared in contact with the fixative. 

Paris-based paint dealer Edouard Adam helped Klein to achieve the desired effect. He advised to use Rhodopas M60A synthetic resin, developed by the pharmaceutical company Rhône-Poulenc.

International Klein Blue color was not patented - it was against to French law, so Klein registered the technology itself.


Klein's “blue period” began several years before the invention of International Klein Blue. So, in 1957, he opened an exhibition in Milan, on which he present 11 absolutely identical blue canvases measuring 78 by 56 cm.

Klein created 194 blue canvases during short career (the artist died at the age of 34 from a heart attack)

The most famous blue works were “anthropometry” (human body science), creation of which was turned into a real performance. Klein poured paint on completely naked girls-models, and then asked them to leave prints on canvas. During such events, guests drank blue cocktails, under the “Monotonous Symphony” - the author's monotonous composition consisted of only one accord.


The actual recording of one of these performances: Yves Klein - Blue Women Art - 1962

After receiving a patent in the summer of 1960, Klein began to create sculptures in blue.


Unfortunately, Yves Klein died in 1962, just two years after the creation of a unique paint...



Effect Restorff or "isolation effect" – psychological principle, the essence of which is that the marked object, such as a red cover book on a shelf with green ones, is more likely to be remembered by others. This feature of human memory is often used by creators of computer games, marketers and designers, artists, photographers and film directors. The main markers are the size, shape and of course colour. So the students took to the habit of marking important lines in textbooks with a marker, because the information that stands out from the rest of the homogeneous text is memorized much better. This effect can seriously affect conversion.

The effect is named in honor of Hedwig Restorff German psychiatrist, who experimentally discovered it in 1933. The participants presented a list of words in which one was different a different color. As a result, the selected word remembered most.

Contrast vs similar colors

Thus, the study “Aesthetic response to color combinations: preference, harmony, and similarity” showed that although the overwhelming majority of consumers prefer similar shades, but them express much sympathy for contrasting palettes with bright color accents.

Another proof of the effective application of the insulation effect are the tests with color-changing buttons. They showed that after changing the button color from green to red, the conversion increased by 21%. Obviously, most of the page is focused on the green palette. This means that the green call to action just merges with the background. Red is a complementary color to green and it provides a sharp visual contrast.


How to use isolation effect in marketing?

● Create useful, meaningful contrast between the promoted product and the cheaper(less quality) counterparts. Surely you have noticed this technique in advertising, when the bright packaging of the same product compare with faded, discolored, “not named” packaging of another product;

● Bright packaging of a fancy shape - something that will highlight your product on the shelf with the same type of competitors. The more nonstandard the product packaging design is, the more likely customers are to pay attention to it.

The effect of isolation in the design

● In the process of developing a site design, highlight the brightly useful buttons that should immediately be noticeable to the visitor, such as “subscribe”, “enter” or “register”

● Change the type of visual effects. For example, if most of the images - the pictures, the contrast is to add a few illustrations, videos, etc.;

● Vary the background color. This is a simple way to emphasize your main ideas;

Volume. Alas, we can not add square meters, but to make an apartment visually more spacious is easy! Light tones deceive our brain, visually expand the space, so even in a small bright room you will feel more spacious. On the contrary, dark or saturated tones will narrow the space.

Levity. How to make massive, bulky wardrobe visually lightweight? There are a few principles that will help you achieve the illusion of levity:

  • Light colors are lightweight than dark
  • Muted colors are lightweight than saturated

Zoning. The combination of different colors is a great way to divide the space into zones: to separate the kitchen from the corridor, to highlight the working area and recreation area.
