Re: Making the web (and beyond) a better place for the colorblind
#2I love the way the examples are shown on this website. Very clear and compelling way to demonstrate the issues that come with colourblindness.
A simple heuristic I use is to think about a display in black and white. There should be a way to clearly distinguish or establish contrast between two items (ie. pattern fills in charts)

#3A small free tool for OS X I found useful is Sim Daltonism[1]
Sim Daltonism is a color blindness simulator for Mac OS X. It filters in real-time the area around the mouse pointer and displays the result ” as seen by a color blind person ” in a floating palette.
If anybody has information about how people with limited color vision perceive the aesthetical side of colors (e.g. how well colors go together in a web site palette) I would love to read about it.

#4Shouldn't display drivers have a "color blind" mode that would alter colors to make them perceptible? It seems an overkill to ask for the whole web to change.

#5Good stuff, sent him an email with suggestions, any more?

Hi Tom, I'm a developer and one of my best friends is colorblind, so I'm onboard. Suggestion - your site clearly demonstrates the problem, but it would be helpful to make it the go-to place for solutions too.
How about starting a list of colorblind-friendly color schemes, for starters? Something those of us who don't need convincing but do need solutions can pull up whenever we're starting a new project and pick the scheme from?
Lots of tools for colorschemes on the web:

In the meantime, any developer can make their own site more color-blind friendly without waiting for the drivers or the whole web to change. Why wait for someone else to solve a problem you can solve right now?

I don't think it's as easy as you make it sound. The hypothetical driver would need to map everythink produced for "standard" trichromatic vision "down" to dichromatic vision in a meaningful way, maintaining contrast where it is relevant, but how should the driver know? (Maybe I am overestimating the technical challenge, so please correct me if I am wrong)
I think the solution can only be to make sure semantically relevant differences in color (e.g. different positions in a chart) can be identified by people with dichromatic vision, e.g. by not using the popular disticton of light red vs. light green. Quickly viewing a design through one of those filter programs is no big tasks and should be part of basic accessibility checks.
This doesn't mean you can't use all kinds of colors when they are not relevant to understanding, [edit: removed direct reference to deleted parent content]

Oops i deleted the comment hastily. I don't see the reason why it's impossible to calibrate a mapping according to the specific user's color blindness. That should be enough to cover most cases, apart from the cases where you are actually asked things like "punch the red monkey"

#10I'm currently working with the presentation team on a console video game and I've known that we were going to have to address colourblindness in some fashion. This is a fantastic website and perfect for sending out to the team to get people caught up on the issue so that we can start a discussion of how we can make our interface really colourblind friendly.
Currently the teams in our battle mode are identified purely by colour and so this is immediately a potential issue that we'll have to double check to ensure that our colour choices are ok.
The wordfeud example shows that it's possible to create a unique colour scheme for the colourblind even with the more limited palette. A good addition for this site would be a reference guide on where a designer should start when selecting these colours and what will completely not work and should be avoided.
