Kendo UI for jQuery
The jQuery ColorGradient is one of Kendo UI’s collection of color picker components. Instead of a pallet of predefined colors, it renders a gradient from which users click and pick. Slider inputs for hue and alpha and manual HEX and RGB inputs help users pinpoint the color they desire.
The jQuery ColorGradient provides text input fields for users to select colors in either RBG or Hex formats. Switching them is only a matter of choosing from a drop down.
To assist you in creating accessible web pages, the jQuery ColorGradient includes a contrast tool. This tool will analyze the contrast ratio between two colors, visualize it and output a pass/fail report for WCAG standards.
The Kendo UI for jQuery ColorGradient comes with support for keyboard navigation out of the box to help users navigate and select colors using just the keyboard.
