RCWebColorPicker is a simple color picker for Mac OS X 10.0 or higher that displays the red, green, and blue values in HTML-friendly hexadecimal values. It also allows a user to restrict the sliders to only allow the 216 web-safe colors.

RCWebColorPicker should show up in the color panel of any Cocoa and many Carbon applications that have one.


One screenshot anyways. When "Web colors only" is checked, the sliders will limit selection to web-safe colors (i.e. values at the tick marks).


RCWebColorPicker is freeware. Please see our About page for more information.
