    The French law of 11 February 2005 guarantees accessibility to everything for everyone. Braille and relief signage adapted to the needs of the blind and those with visual impairments must be used in buildings that are accessible to the public.

    The colours used must be contrasted with the background and limited to two.

    The difference in contrast between the support base used and the colours used must be at least 70%.
