I personally prefer to choose the Color Code by myself but when you suggest multiple sketches can be an help to dont repeat yourself.
the best tool is free to use on-line:
colorschemedesigner
with Html / Css / text / ACO (photoshop palette) / GPL (Gimp palette!) generator to save the color schem

Linux tools:
Firefox Plugin: Palette Grabber 0.4.1 [testing now come back visit us to know more!]

http://registry.gimp.org/node/15833 [Python plugin!]

AGAVE
ich spiele gerade mit diesen color code generator Agave
Agave is nothing special is only 1,262 kb big

I have found a Python plugin to let Agave run in Gimp ::
Color Scheme Helper for Gimp

A Python plugin that start the color scheme designer Agava for creating a new color scheme. The created color scheme can be saved as a Gimp color palette and loaded into Gimp.
In the software engine the only pretty idea is the contrast between text-background calculation…
changing the color automatically shows if is better a white or a black text on top of this color: Agave calculate if the bg color has a number higher then 555555 THEN the text is black and the opposite when the choosed gamma color is darker then 555555 the text will be white.

I m using AGAVE  as teaching tool, to show direct example of text contrast to graphic design students.

#tk: based on math – hmm naja interesting algorithm anyway … hehe ya should generate for special things like: body-font, screen-bgcolor, … i want some faders that automagically apply like livestyle to the site 😀 with correct pi and phi equations.

Color Scheme Generator version 3.51  has many new features!

The preview page I dont really like it use the colors in illogical contrast with the background

   Wow! the colorschemedesigner is really impressive. so many good algorithms and +contrast +saturation and much more.

   its programmed in jQuery and could be integrated into a faramework or the livestyle CSS refresher.

   unfortunately it is released under a licence, which does not allow
   usage in other (specially commercial) projects 🙁
