I prefer Snook's Colour Contrast Check:

http://snook.ca/technical/colour_contrast/colour.html

as it allows you to test the foreground/background colour combinations for compliance with WCAG 2.0, which is the internationally recognised standard for accessibility of web pages.

I checked the front page of Vikidia - the worst spot seemed to be part of the "Star article" which had black text on a background of #24B88E. That passes most of the WCAG standards, with the exception of the colour difference - so that's acceptable for most purposes. The rest of the wiki is very clean with good legibility - well done!

Here's a tool for testing web sites for suitability for colour-blind users. http://colorfilter.wickline.org/
It may be worth creating a mockup on a public server and testing.
Good luck with the project, Mathias- glad to see so many of the projects discussed at EduWiki are actually happening.

It's an interesting idea. The colours on the main page really stand out, though I wonder how easy it will be for people with colour blindness to read. Has it been tested for that?

The current colours on the main page were made by a 15 years old user of (mainly) Vikidia in French, we just make it in a wiki way you know ! (Would you believe it can work ? ;-) )

    Hi,

    Since I was able and glad to come in EduWiki 2013 in Cardiff, to
    make a presentation about the Wikikids proposal :
    https://wikimedia.org.uk/wiki/EduWiki_Conference_2013/Abstracts#Wikikids_-_Mathias_Damour
    we have gone forward and we are about to launch Vikidia in English
    on the 28th of February.
    It's already open with restricted access, and the early editors
    mainly come from the other Vikidias and from WikiKids.nl.

    Nevertheless, I would be glad that Wikimedia UK or some of it's
    member gets involved and supports this project, (Wikimedia France
    does), provided that if it makes its way properly, it can have a
    great impact for our goals.

    If you want to have a look, it's http://en.vikidia.org and the
    codes are "vikidia" and "aidikiv"
    We have set up most of the basic/frame pages and we better them
    before launching the wiki.
    Here they are : http://en.vikidia.org/wiki/Vikidia:Talk/2014/8

    Here is a scratch communiqué/launching message :
    May you be interested in this project and spread, advice or help it ?

    *****************************************************

    A Vikidia opens today, let's built a children wiki encyclopedia in
    English !

    Vikidia is the equivalent of Wikipedia for children: an online
    encyclopedic project, for 8-13 year-old readers, open to
    contributors of any age. It was launched in November 2006 in
    French, then in Spanish, Italian, Russian and now English. It aims
    both to offer a suitable corpus of knowledge for children and to
    let some of them, as well as teenagers them be involved in
    building it. It is very close to Wikipedia in its aim and
    functioning, except the age range.

    Such wikis have proven their sustainability, relevance and
    success, the two biggest ones this model being Vikidia in French
    and WikiKids.nl in Dutch, with respectively 16000 and 14000
    articles and hundreds of thousand readers every month.

    Many children already use Wikipedia daily, for the substantial
    content and the well known convenient way it is to find material
    on any subject. However, the level of Wikipedia articles makes
    them hardly accessible for children or even other people on some
    subjects and they may read it for lack of a better resource.
    There is some television programs for children, some books, some
    movies for children and even some newspapers and magazines. It
    would be unsound to consider that they couldn't make a great use
    of a children encyclopedia. Many children really need and
    appreciate when it does exist to have a more readable content for
    them. They tell it on the French Vikidia guestbook, on which the
    main remarks are that they like it and that they would like to
    find more articles and more content in most articles. It is not
    designed only for children but for everybody who want a simple
    explanation on a subject. That mean that the content must be
    suitable for 8–13 years old children, based on the general
    perception of what is or not considered as possibly offensive for
    this age range. That also mean that we take each subject seriously
    in order to build a quality and substantial documentary resource.

    To offer to some children and teenagers to take part in such a
    resource and to be active in the building process is also
    obviously a matter of empowerment. The mere possibility to add
    something may also change one child's motivation for the content
    as a reader.

    Everybody is invited to edit Vikidia without age restrictions.
    There are no mandatory or forbidden roles or status related to the
    users real ages. Vikidia both needs grown-up contributions and
    enable children and teenagers to write and to be involved in
    building the encyclopedia. Young people can also be involved
    within educational activities organised by schools. They may gain
    some digital/media literacy by learning about the functioning of a
    resource they will use extensively few years later: Wikipedia,
    although the goal is still to create content an the "knowledge
    resource" benefit of such a project: school projects are welcomed
    provided they consider the wiki's rules and content objectives.

    - Adults involvement is essential for building content that is of
    quality and significance, fostering basic maintenance: to watch
    and ensure a certain stability in the functioning of the wiki,
    - children's involvement, even when they don't produce very long
    articles, let appear works on subjects that interest their peers,
    it responds to their aspirations and their desire to participate
    and they definitely take their share in growing the content and in
    maintenance tasks,
    - older children, teenagers that don't (yet) edit Wikipedia can
    have the chance to do it here, and to make a good work. The
    advantage is both the amount of work they can bring, and what this
    work can bring to them, like for the younger ones and like any
    Wikipedia editor.

    Vikidia representatives used to work on a proposal to be adopted
    within a multilingual Wikikids project. They no longer ask for it
    and decided to remain it independent from the Wikimedia Foundation
    and now to open a Vikidia in English.
