So, now I just checked with wikipedia and my confusion became quite clear: http://en.wikipedia.org/wiki/Cyan The cyan I learned, (from a computer graphics background), wikipedia calls "electric cyan", "web color aqua", "electrical blue". This is a secondary color in an additive color system with red, green, and blue primaries, (it is 100% green + 100% blue). That's the cyan I've always known and loved. Meanwhile, there's another color there called "process cyan", "pigment cyan", or "printer's cyan" which is a primary color in the subtractive CMY system used for printing. And indeed _this_ color, (meaning, the particular RGB formulation that wikipedia demonstrates), does look very much like a "cyan" pyramid from Xeno set I have here.
I must disagree with you here. I checked out the Wikipedia page that you linked to, and held up a Cyan Icehouse piece to my computer monitor, and to my eyes the color of the pyramid is closer to the "electric cyan" color. In fact, the effect is more pronounced if you pick up a large piece and look *through* it at the web page; the color of the piece effectively filters out the "electric cyan" colored rectangle from the page (especially if you look through two faces simultaneously instead of just one), while the "process cyan" rectangle shows through as a darker blue.
Of course, the colors on my monitor might vary from those on yours. -- Karl von Laudermann karlvonl@xxxxxxx http://www.geocities.com/~karlvonl/
