Actually, I've never found a fully reliable way of creating dither-free colors
on all systems, no matter what some of the experts claim.
I went through this with a project I'm working on now: used only colors
from the "browser-safe palette", kept the images very simple and clean,
checked them at various resolutions on my system; but the client still
said, "Navigation graphics are dithering noticably on some of our 256-color
systems here. Though they're better on others."
I admit that my eyes tend to glaze over whenever I spend too much time
reading up on the topic of "browsers and colors", and so I may not fully
grasp all of the nuances, but my general understanding is this:
"Different browsers render colors differently. Netscape, specifically, has a
set of 216 colors that it will attempt to use when displaying graphics.
Though this varies depending on your operating system. Different video
cards display color differently too. A video card that displays 256 colors
may not display the *same* 256 colors as another card does. And so on."
Or, take this quote from WebReview:
"There is, in fact, no one universal 8-bit palette that will not dither on all
platforms. There is, however, a 216-color palette that will not dither on
most.
"The problem is that different platforms use different color palettes.
Netscape and other applications use a 256-color palette on Macs and X-
windows, a reduced palette on Windows, and UNIX varies the palette
according to how many colors are available. Note: Netscape 4.0 Mac uses
the 216-color "non-dithering" palette, not the Mac's system palette."
It's at times like this that my eyes usually start to glaze over, sigh...
anyone have some "failsafe" tips on this topic?
