Internet for people with poor color perception and more. The idea of ​​solving the problem globally

Hello dear habrosociety! A couple of days ago at night I was visited by a very interesting idea, namely: how to make the Internet more accessible for visually impaired and people suffering from color perception disorders (color blind). About how we can help them We (developers, designers, UI / UX specialists) and creators of browsers can be found under the cat. So, perhaps, Habrahabr looks for some of us.


And how do you see Habrahabr {userName} ?

On the state of affairs

Today, when search engines and sites know almost everything about you, to give you targeted SERPs, advertisements and anything else except what you are actually looking for (maybe I exaggerate, but many adhere to this point of view). At this very time, visually impaired people still need to manually search for a link to the transition to an adapted version of the site. At this very time, designers and UI / UX specialists are trying to choose colors so that they are equally well accepted by ordinary users and color blind. Thousands of copies are broken on this field. This task is not an easy one, considering how many types of color perception disorders exist:

  • Protanopia (Red-Blind)
  • Deuteranopia (Green-Blind)
  • Tritanopia (Blue-Blind)
  • Protanomaly (Red-Weak)
  • Deuteranomaly (Green-Weak)
  • Tritanomaly (Blue-Weak)
  • Achromatopsia (Rod Monochromacy)
  • Blue cone monochromacy

Read more on wikipedia: Color Blindness . Most color blind people have problems with the perception of red or green, but to ignore the rest is somehow wrong. But if you try to please everyone (this approach never works), then nothing will work out for you, adapting the colors for one version of the violation, we will spoil the perception for another. Such are the things. And this is how the colors of the rainbow * look for people with some color disturbances:
Well, now you know how the LGBT flag looks for color blind. Although it is also a flag of the world, the Jewish Autonomous Republic of the Russian Federation (I was corrected, there is still 7 colors) and, as it turned out, a lot more then . But now for some reason it is associated with all with only one ...
UPD: I myself was surprised when I saw this flag on Wikipedia as an example, but trolling is actually credible. By the way, they have one rainbow color missing on the flag, guess which =)

About the extent of the problem

Or maybe figs with him, before you didn’t pay attention to it, so now you can? Well, firstly, earlier these problems were also paid attention to, but, unfortunately, not as often as it should be. From the recent one you can recall how the Moscow metro scheme was adapted, you can read about it at Ludwig on LiveJournal . But I repeat that the scale is not the same, well, do not make the same version of the site with an alternative color scheme in fact, although ... we will come back to this. Now let's see how many people around us with color perception disorders.
Gender Protanomaly Deuteranomaly Protanopia Deuteranopia
Male 1.08% 4.63% 1.01% 1.27%
Female 0.03% 0.36% 0.02% 0.01%

The tablet is taken from the book Color Vision: From Genes to Perception (Karl R. Gegenfurtner, Lindsay T. Sharpe).
Total, we have about 8% of the male population and 0.5% of the female . For comparison, the population of Russia is about 2% (140 million / 7 billion). Draw your own conclusions.

How to make the internet better

So, what occurred to me at 2 a.m.? The idea was to add additional settings to all browsers (a couple of extra checkboxes), in which a person, if desired, could select the desired item (visually impaired, some kind of color blindness). And then this mode / property / attribute could be used by developers on sites. Use could be through JavaScript , but even better, in my opinion, add a new media type for media queries to be able to adapt the content via the CSS . By the way, there are already types aural (Used for speech and sound synthesizers) and braille (Used for braille tactile feedback devices), so why not add a couple more? Here I want to focus on the fact that this approach will help different categories of users, and not just color blind and visually impaired. I mean, today unusual input / output devices are appearing now and then, and this can also be taken into account, but this is the topic of a separate article.

Now about why I write all this on a hub There are people here who can influence browser development! At least this pepelsbey (Opera) and forgotten (Yandex), there are representatives of other companies. AND forgotten also a member of the W3C TAG . There are also many people on whom it depends directly on whether to adapt the site or not. And how many here are those who are one way or another engaged in web design, I don’t even say. Well and most importantly, if you can adapt it just by writing additional media query , the number of adapted materials on the network should increase significantly. After all, if something can be improved by small forces, why not do it? And this is the main point.

Dry residue

The essence of my idea is to deliver targeted content, as far as we are realizing the option I have proposed, I suggest discussing it in the comments, I would also like to see criticism, other solutions and so on. From experts, I would like to hear the viability of this idea and options for technical implementation. In general, let's make the Internet a little better together !
