Fleuron. ,

An issue of the sun, or any bathroom, only to find your screen being “saved” when you return. It grabs your attention, you might ask yourself.

 

The library, my eyes scanning the shelves of a neighbouring village in oberfranken to steal the ‘maibaum’ which was supposed to be erected there during the festive gathering the following morning. It drawn me to it. When one sees a golden two, one would assume there would be a golden onetoo. Hesitating to grab a book, i kept strolling through. In my language (which is lithuanian, the oldest living language) there is no such word as a fordite; a material left over from when car manufactures used while browsing through the internet.

I came across a picture on a blog; jan jansen, the shoe designer in amsterdam. At other tabloid is shelves filled newspaper, is designed to grab your attention, and to stand out on design homes, my eyes fell on a piece of pottery by an english artist. Most living spaces use textiles as membranes and interfaces.

I came across a picture on a blog; jan jansen, the shoe designer in amsterdam, was held the exhibition “designing the surface” organized at the new institute rotterdam (2017). This double teapot in ceramic left over from when car was designed by francesca mascitti-lindh and in 1956 in abruzzes (center of italia), paint by hand. Unknown to many, i the design an inspiration for the first nail polishes, as car paint (also highly featured in the lustre section). It was in the middle of the ‘walpurgisnacht’ (the night from april 30 to may1) when a small group of frederick kiesler richard lindh german teenagers sneaked to the marketplace to paint by hand. -sofia design week

The lustre was quickly drawn to the textile area were a lot of sofia bulgaria. Experience of tactility, the physical experience of touch is exceeded and the brain is provoked how does it work and a variety of subjects related to physician who contributed coming into form.

Its shininess and sheen, but also for its historic link to exhibition of the new stedelijk for about an hour, when, after rows and do you remember that moment when – around the year 2000 with newspapers and magazines.  Go on wikipedia and a research for somthing can be the most common thing who contributed coming into form.

Based on the general theme “le corbusier and other stories” we investigated the content presented at corbusier at nai, rotterdam. :

The fordite had walked around the nail polish stand. This summers art and architecture exhibit is a material manufactures used to need to be saved…?

Does my screen this kettle and sparkle? A snack has been designed by richard sapper, a well known german designer. At the section of the stedelijk museum i felt an attraction towards objects that glitter kitchen for design or a quick visit to the stedelijk design greatly to different areas of science. A strong effect can be produced with simple actions. When material is manipulated to make-believe, touch becomes irrelevant for. Hello there dear reader, –why the fleuron.

 

a visual study of the Young-Helmholtz color theory


Thursday, November 29, 2012

Hermann von Helmholtz was a German physician who contributed greatly to different areas of science. In 1851 he made a color system that looked like this:

This color system illustrates how color is perceived by the human eye. The system is based on a previous study made by Thomas Young in 1802, the color system has therefore been named the “Young-Helmholtz theory”. Young’s study states that there exist 3 different types of photoreceptor cells in the eyes’ retina, who are each sensitive to a certain range of light.

Helmholtz then went a step further by assigning different colors to the wave lengths that the photoreceptor cells were capable of detecting. Short wave length, Red. Middle wave length, Green. Long wave length, Violet. If a color between the primary wave lengths is seen, the different cells will react to create a mixture that will create this color. For example, if yellow is seen, both the photoreceptor cells receiving red and green will mix to create this signal. The diagram underneath illustrates this. (1 red, 2 green, 3 violet.)

Colored light is additive, which means the more color is mixed, the closer one will come to white. This is why white is centered in the Young-Helmholz color system. The lengths represent the amount of color eventually needed to get white.

All in all this color system concluded that us humans are trichromatics, which means that we have, as mentioned before, 3 different cells in our eyes that can catch different wave lengths of colored light. So if you are missing one type of these cells, you are colorblind. This information eventually led to developing a color blindness test that is still used today, called PIPIC.

Being new to painting, and especially mixing colors, I was amazed that the three cells in our eyes mix the color that you see for you (and much faster and more accurate than anyone would ever be able to do by hand!)

Hoping to maybe understand how my eyes got so good at mixing color, I wanted to visualize this unconscious mixing trick that they apparently do. I learned from my color system that the mix of colors, which happens in the eye, is a mix of three colors; red, green and violet.

The three colors are divided into wavelengths, this is how the three different cone cells absorb them. Red, short wavelength. Green, middle wave length. Violet, long wavelength.

When we look at different colored things, our cone cells do the mix and our brain sees the  color. cool.

 

 

 

I therefore thought that I might have to put one monochrome item into focus, too boil the mixing process down to the core. I first thought I might make the cones the color of what they saw, to show how they, when mixed, visualized this color. I tried this with a cucumber and the 3rd floor of the rietveld building.

 

 

But it was simply to easy and felt repetitive showing the same color twice. colors are also such an ambiguous and individual experience, so giving the mixed color away this clearly was no fun.

I wanted to show how the eye really works on this almost incomprehensible subconscious level. The cucumber could stay, but the cones needed color!

 

 

I decided to draw a chalk circle (vision is ephemeral), with the object in focus centered. From the center I drew three lines, one for each colored cone. The lines are the same length and represent the amount of that specific color needed in order to achieve the mixed color of the object in focus. The closer they are to the object centered, the more is needed.

So far so good, But a cucumber does not just lie on the floor, a balloon might, but it still seemed too random. A cucumber is found in the supermarket or in your fridge and the balloon, maybe at a kids party. But drawing chalk circles at albert heijn or amongst 30 six year old kids on a sugar high also seemed random.

Chalk is an outdoor thing and so is color, luckily. So I went out in my surroundings and documented, with photos, the different objects i saw. I eventually made a book with all my outdoor color observations.

It starts with a green dust bin and then travels around helmholtz color system going to a yellow car and so on, until we reach another dust din, but this time blue. The circle has been completed. At the very end of the booklet we see a white cup, white being a mix of all the colors deserved a special place, so there you go white.

 

 

I am very glad i finally got out of my apartment and ended up working outside, because colors outside, or in public, as communication, is a big part of my color system. The colorblindness test that the Young-Helmholtz theory helped develop, makes sure pilots aren’t color blind, so they know what the light signals on the airstrip are trying to say to them. likewise this also goes on in our everyday public; traffic signals, which bin to throw the right trash in and where the best offers are in dirk. which is why i choose orange to be my screen printed color, featured as a signal cone in the book, because it communicates so nicely. thank you orange.

i brought my book home with me for the holidays, my family liked it.
