The Installation includes six exhibits, at first sight looking trivial, each object incorporates a very unique ability. Each is accompanied with a little story, all completely concealing the existence of technical components such as speakers or sensors, only small connection ports as well as the uniform black finishing point to thier unusual abilities. Watch video below for demo.

In form and functionalty all these exhibits pursue John Maeda’s „Simplicity“. They are enjoying to use, they are surprising and one wants to explore and investigate them.


Base on the color pallet that was propose…

I did a CMYK Xylphone Test the aim of this is to see if the colors are more distinguishable from each other Through Vischeck


As you can see the red and green colors from the original image appear to have similar shades of brown. The adjusted color palette shows that Red and Green is more distinguishable compared to the original image

This is a proposal of color pallet that is

1: unambiguous both to colorblinds and non-colorblinds,
2: with vivid colors so that color names are easy to identify,
3: can be printable with similar color both on screen and when printed.

  • For red, vermilion is used since it is recognizable also to protanopes.
  • Colors between yellow and green are all avoided, since they are indistinguishable with yellow and orange.
  • For green, bluish green is chosen so that it won’t be confused with red or brown.
  • Since violet is close to blue and appear the same to colorblinds, reddish purple is chosen.
  • Between vermilion and yellow, three colors with different apparent intensity is selected.
  • Sky blue and blue are chosen so that they are distinguishable with there difference in brightness and saturation.
  • Even for non-coloblinds, thin lines and small characters in blue and yellow are hard read. For thin lines and small objects, use darker blue and orange is preferable to sky blue and yellow.

When combining colors from this pallet,

  • Use “warm” and “cool” colors alternatively.
  • When using two warm colors or two cool colors, put distinct differences in brightness or saturation.
  • Avoid combination of colors with low saturation or low brightness.

Colorblindness is not a total loss of color vision. Colorblind people can recognize a wide ranges of colors. But certain ranges of colors are hard to distinguish.

The frequency of colorblindness is fairly high. One in twelve Caucasian (8%), one in 20 Asian (5%), and one in 25 African (4%) males are so-called “red-green” colorblind. It is commoner than AB blood group.

3(+1) principles of Color Universal Design

1.Choose color schemes that can be easily identified by people with all types of color vision, in consideration with the actual lighting conditions and usage environment.

2. Use not only different colors but also a combination of different shapes, positions, line types and coloring patterns, to ensure that information is conveyed to all users including those who cannot distinguish differences in color.

3.Clearly state color names where users are expected to use color names in communication.

4. Moreover, aim for visually friendly and beautiful designs.

#01 99% of all colorblind people are not really color blind but color deficient; the term color blindness is misleading

#02 Red-green color blindness is a combination of red-blindness (protan defects)and green-blindness (deutan defects).

#03 Color blindness is more prevalent among males than females, because the most common form of color vision deficiency is encoded on the X sex chromosome.

#04 “What color is this?” is the most annoying question you can ask your colorblind friend.

#05 There are three main types of color vision deficiency: protan, deutan, andtritan defects  

#06 Strongly colorblind people might only be able to tell about 20 hues apart from each other, with normal color vision this number raises to more than 100 different hues.

#07 Colored lenses or glasses can improve color discrimination in your problem areas but can not give you back normal color vision.

#08 Ishihara plates are the best known color blindness tests, but they are not the most accurate ones.

#09 About 8% of all men are suffering from color blindness.

#10 Severity of color blindness is usually divided into the following four categories: slightly, moderate, strong, and absolute.

#11 The terms protandeutan, and tritan are Greek and translate to first, second, and third.

#12 A father can’t pass his red green color blindness on to his sons.

#13 Dogs are not colorblind 

#14 Color vision deficiency would be a much better term; but it is not as easy to pronounce compared to color blindness.

#15 There are people which are really suffering from complete color blindness, which is called achromatopsia or monochromacy.

#16 Blue-yellow color blindness would be better called blue-green color blindness, as this are more the problem colors.

#17 There exists every nuance of color vision deficiency severity, starting fromalmost normal color vision up to complete color blindness.

#18 Protanopiadeuteranopia, and tritanopia are types of dichromacy, which means you have only two different color receptors (cones) compared to three with normal color vision.

#19 If a woman is red-green colorblind, all her sons will also be colorblind.

#20 Colorblind people feel handicapped in everyday life, and almost nobody recognizes this.

#21 99% of all colorblind people are suffering from red-green color blindness.

#22 When using color correcting lenses you are wearing two differently colored lenses in your eyes.

#23 Red-green color blindness is a recessive sex linked trait, which causes more men to be colorblind than women.

#24 John Dalton wrote the first known scientific paper regarding color blindness.

#25 Protanomalydeuteranomaly, and tritanomaly are types of anomalous trichromacy, which means you have three different color receptors (cones) like people with normal color vision but one of them is shifted in its peak.

#26 In certain countries you need normal color vision to get a drivers license.

#27 Deuteranomaly—one form of red-green color blindness—is by far the most common form of color blindness.

#28 More women than men are carriers of color blindness, even though they are not colorblind themselves.

#29 Some people get rejected from a job assignment because of their color vision deficiency.

#30 About 0.5% of all women are suffering from color blindness.

#31 Blue-yellow color blindness is a dominant not sex linked trait, which means both men and women are equally affected.

#32 Red-green color blindness doesn’t mean that you are only mixing up red and green colors, but the whole color spectrum can cause you problems.

#33 The anomaloscope is the most accurate color blindness test known today.

#34 Police officerfirefighter, and airline pilot are the most famous jobs which require normal color vision.

#35 There is no treatment or cure for color blindness 

#36 Pseudoisochromatic plates were introduced by Professor J. Stilling of Strassburg in 1883; the Ishihara plates by Dr. Shinobu Ishihara followed almost half a century later.

#37 Different chromosomes are involved as sources for the different types of color vision deficiency.

#38 Women can also suffer from color vision deficiency

#39 Monochromacy—also called achromatopsia—means you have only one type of color receptors (cones) in your eyes.

#40 Color blindness is also called Daltonism, after the scientist John Dalton.

#41 The most often used types of color blindness tests are: pseudoisochromatic platesarrangement test, and the anomaloscope.

#42 Better color vision deficiency terms would be: red-blindness for protanopia, red-weakness for protanomaly, green-blindness for deuteranopia, green-weakness for deuteranomaly, blue-blindness for tritanopia, and blue-weakness fortritanomaly.

#43 John Dalton believed his whole life that the cause of his color blindness is acolored fluid inside his eye balls.

#44 Many colorblind people have problems with matching clothes and buying ripe bananas.

#45 Quite a lot of people with normal color vision can’t pass an Ishihara plates testfree of errors.

#46 The International Colour Vision Society is scientifically investigating every aspect of color vision and color vision deficiency.

#47 Confusion lines of the CIE 1931 color space show exactly the colors of confusion for all forms of color blindness.

#48 Only a whole battery of color blindness tests can reveal the true type and severity of your color vision deficiency.

#49 John Dalton was also colorblind himself.

#50 A Colblindor is a colorblind person who learned to enjoy his colorblind life 😉
