The RGB slider implements the YUI Slider Control to create three sliders which, between them, generate an RGB color. The background color of each slider is also dynamically modified to reflect the colors that could be generated by moving a single slider; this affords greater visual feedback to the user and allows her to have a quicker intuitive sense about how to get the desired result.
(Note: YUI also includes a full Color Picker Control with a complete set of configurable options.)
Note: You are viewing this example in debug mode with logging enabled. This can significantly slow performance.
All YUI 2.x users should review the YUI 2.8.2 security bulletin, which discusses a vulnerability present in YUI 2.4.0-2.8.1.
