Online Color Picker and Color Conversion Tool

Just a few hours ago I finished and deployed my new online service and very first endeavor in the interesting world of colors and color theory. Say hi to AcidJs.ColorConverter!


  • Native HTML5 color picker.
  • Color conversion to and from HEX, RGB, HSL, CMYK, HSV,  etc.
  • Color tints, tones and shades.
  • CMYK and RGB color charts, powered by Google Charts.
  • Inspirational color schemes.
  • Detailed information about the selected color.
  • Option to save the raw JSON data, containing the details of the selected color.
  • About 900 named color equivalents.

Built on top of HTML5 WebComponents (AcidJs.XTabs and AcidJs.XOverlay), and utilizing Object.observe() and the (not-so-new) input “color” type (sorry, no fallback for browsers, which do not support it and that’s on purpose!) and using the data from the brilliant ColorHexa service, which I transform to JSON via the REST API running on my server.


The color picker:


Raw data viewer:


RGB and CMYK color charts


Color conversions table


Advanced view – shades, tints, tones and schemes


Editor tab


Check it on this page and have fun!

It is easy to configure via a small, but powerful API and events, and comes with stunning and realistic desktop-like 3D CSS3 animations.


The tiles can be used as placeholder of virtually anything – from simple text, to sophisticated markup and forms.

HTML5 Canvas Gauge Component

Try Semtex – the new HTML5, CSS3 and JavaScript UI framework!

I am happy to announce that I’ve just finished the new widget that is already part of Acid.JS Web.UI – the AcidJs.Gauge class (demo).

AcidJs.Gauge is a JavaScript widget, using the HTML5 canvas element to draw interactive gauges with various configuration options on the page with a simple, but yet powerful API.


All major browsers are supported, and for older browsers, which do not support canvas we have a nice fallback.

You can check the demo of this page. Have fun!
