Some good articles I have archived on my site regarding this topic: Web-Graphics: A Review of Web Based Color Pickers Author: Nathan Steiner - This review includes some core details about many of the currently available and popular online color picking tools, so that you can choose which tool has the right combination of features for the way you work. FULL ARTICLE: http://www.makovision.com/m/tr.asp?l=1724 Colorcom: Color and Usability Author: J.L. Morton - This points to another usability issue. In the world of computers, it's known as user-interface design. From the visual interface of the operating system to the software components and peripherals, colors and symbols help you find your way and get the job done. In the same way that color works in an international airport, color combined with shapes and symbols will mean the difference between successful computer-human interaction or confusion.

The theory may not let you instantly select a color scheme, but it will certainly lead you along the right path.

Working with the colors and tone of our design will help us create the emotion we desire and if we don't take effort to work with it, we'll create the wrong impression, possibly alienating the very readers we wish to attract. We should take into consideration the different emotional, symbolic, and cultural meanings of colors when designing a Web site theme.

Thanks to Ben who's found the RGB2HSV function: http://www.cs.rit.edu/~ncs/color/t_convert.html Heather, I was not interrested in getting the inverse of a RGB color, because I already worked the solution out, it wasn't that hard :-) But as far as my art theory goes, inverse colours are not specialy useful visually, except for black and white.. (perhaps I don't see the obvious usefulness of inverse colours?) It was just that I recently heard of a complimentary color to each color, and I thought I could use that in order to create visually pleasing sites without choosing the base colour myself. Since I'll do it in PHP, I think once you have converted your RGB values to HSV, you have to do a rotation of the H angle, change a little bit (random offset) S and V values for not looking too rigid in the choice of colours. Then you'll have to convert back your new HSV values to RGB in order to use them in HTML table borders and likewise graphical elements on your page. from what I understood, the rotation of H angle should be 180° I take this from this page: http://www.liquisoft.com/color.html I think it's correct, I'll report to evolt about that after my tests if it's wrong. I'll do testing on toulonparadise.com as soon as I have the courage, surely next year :-) Thanks again Cordialement, __ Alliax ~CV : http://LingoParadise.com/cv.php Un site pour Toulon : http://www.ToulonParadise.com Un site pour Renaud : http://www.rfaucilhon.com Un site pour Director : http://www.LingoParadise.com -- For unsubscribe and other options, including the Tip Harvester and archive of TheList go to: http://lists.evolt.org Workers of the Web, evolt !
