Creation de palette graphique pour design, dessin etc...

Sim Daltonisme est un simulateur de daltonisme pour Mac OS X qui vous permet de filtrer en temps réel la zone entourant le pointeur de la souris et d’en afficher le résultat — tel que vu par une personne daltonienne — dans une palette flottante.

Outil pour choisir sa palette de couleurs

'd like to express my appreciation to pair.com for donating a dedicated server to host this utility. Use the colorblind colorlab to select safe colors earlier in the design process. Learn more about colorblindness in this Wikipedia entry. This tool is still in development, but feedback is welcome while I work on it. If you only use one filter, use the grayscale filter which will not only point out potential problem areas, but will also let you see more clearly which areas the filter is unable to process.

The Colour Contrast Check Tool allows to specify a foreground and a background colour and determine if they provide enough of a contrast "when viewed by someone having color deficits or when viewed on a black and white screen"[W3C]. The tool will indicate that the colours pass the test if both the colour difference and the brightness difference exceed their threshold. It will indicate that it sort of passes if only one of the two values exceed their threshold. And finally, it'll fail to pass if neither value exceeds its threshold.
