Cet outil vous permet de définir des couleurs web personnalisées.

L'outil offre également une conversion facile entre les différents formats de couleurs CSS : couleurs hexadécimales, RVB (Rouge, Vert, Bleu) (aussi appelé RGB en anglais) et TSL (Teinte, Saturation Luminosité) (aussi appelé HSL en anglais). Le canal Alpha est également pris en charge pour les formats RGB (rgba) et HSL (hsla).

Chaque couleur est prédéfinie dans les 3 formats standard CSS.

En fonction de la couleur courante, une palette de couleurs est générée sur une échelle TSL ainsi que sur une échelle de transparence (en faisant varier l'alpha).

Le sélecteur peut être réglé sur les formats HSL ou HSV (valeur de teinte et staturation).
