Howdy Sarah, The topic of color interests me very much as I used to teach color theory seminars to weavers..took 'em right to the edge of quantum mechanics and then stopped because they all had that glazed look in the eyes.And if Paul will overlook this bit of bad logic, which I am probably becoming famous for in many circles...the following suggests itself.. Black is a combination of all colors, and White is a combination of all colors Ergo, black is white. As a weaver/dyer, when given time, I find it important to work both with subtractive and additive color theories to analyze objects that I am trying to get a feel for. I may be able to study an object under full spectrum lighting to find the correct pigment blend, but then it changes when put into context with other objects because of simultaneous contrast, lighting situations, etc. I have used shells for color and design inspiration on many occassions, and I do have a certain affection for the weird ones.(Even thought I can't explain them.) Hvae a colorful day! Patti in New Mexico ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com
