INPUT Color Description:
The color INPUT tag gives you a way to request colors in your web form. The color type collects sRGB color with 8-bit red, green and blue components. Ideally, the browser would display a color well that allows the user to pick the exact color they want to submit.
DTD: HTML5: <!doctype html>
INPUT Color Web Browser Support:
At this time, no browser supports the INPUT color type with a color picker. Instead, they display a text box. You can still use this input type, you will just have to validate that the contents are a color with a script or CGI.
HTML Versions

INPUT Color Special Notes:
The input color tag is not supported in any browsers if you want a color picker displayed, but you can still use this input type and validate that the submitted data is a color. That way, when browsers do start supporting it, your forms won't have to be modified.
