Eric, I hope you don't mind if I reproduce here some links I shared on another newsgroup (comp.databases.filemaker) for determining complementary colors. In some cases, it can be quite educational to review the JavaScript code for these pages.
I think that as a general approach, you probably want to convert to HSL, figure out your colors, then convert back to RGB. Formulas for this can be found at: http://www.easyrgb.com/math.php?MATH=M19#text19 Here are links to other color calculators: ----- http://www.colormatch.dk/ http://meddle.dzygn.com/tests/colors/ A very easy, elegant, visual tool that returns six complementary colors. The first link is the original gem, the second one provides RGB values and precise color entry. ----- http://wellstyled.com/tools/colorscheme2/index-en.html Offers five different styles of color matching ----- http://www.december.com/html/spec/colorschemer.html Offers six different styles of matching, plus a nice preview of a formatted page using the colors. (Requires the free Adobe SVG viewer plug-in from http://www.adobe.com/svg/viewer/install/main.html) ----- http://www.webwhirlers.com/colors/colorwizard.asp Offers seven different matches of color (but requires entry of hex values) ----- http://www.hypergurl.com/colormatch.php Another color mixer that supplies nine compatible colors. (Try clicking on the "Load predefined theme" popup menu and using the scroll wheel on your mouse.) ----- http://colorblender.com/ A very easy to use blender that will also suggest PANTONE(R) colors. ----- For an in-depth look at the theory behind color schemes, and why you might want to use one style of color matching over another, check out: http://www.december.com/html/spec/colorhslhexuse.html Bill "Eric Chatonet" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] > I would like to build a range of harmonised colours in the same tint: > Something like "162,173,215","182,193,235","202,213,255", etc. > As long than a colour value is less than 255, it does not seem to be a > problem as above. > But I don't find out how to calculate consistent values once a value has > reached 255. > Any ideas? _______________________________________________ use-revolution mailing list [email protected] Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution
