Saving A Palette; Using Dithering - MACROMEDIA FIREWORKS 2-USING FIREWORKS Use Manual

Removing edits to colors
Remove any edit made to a color by selecting the color
and choosing Remove Edit from the Options pop-up.
Also, individual edits may be removed by selecting a
color and then deselecting the button of the edit you
wish to remove.
Setting web-safe colors
Web-safe colors are colors that are common to both
Macintosh and Windows platforms. These colors are
not dithered when viewed in a web browser on a
computer display set to 256 colors.
Web-safe colors are indicated on the Palette view with
a small diamond in the center of the swatch, as
shown here:
Fireworks has several methods of applying and using
web-safe colors.
Choose the Web 216 palette to force all colors to
web-safe colors.
Choose the WebSnap Adaptive palette to create an
adaptive palette in which colors that are near in
value to web-safe colors are converted to the closest
web-safe color.
Select a color and click the Web-Safe button, or
choose Snap to Web-Safe from the Options pop-up
to force that color to its closest web-safe equivalent.
Web-safe button
Changing colors to web-safe in the Export Preview does
not effect the actual image, only the exported version of
the image. However, all colors set to web-safe are
retained each time Export Preview is used.

Choose Save Palette from the pop-up next to

The saved palette file can be loaded into the
Swatches panel or used when exporting other
documents.

Using Dithering

Use dithering to approximate colors not in the current
palette. Dithering is especially effective when exporting
images with complex blends or gradients or when
exporting photographic images to an indexed image
format, such as GIF.
Note: Dithering can greatly increase file size, especially
the size of a GIF.
To dither the exported image, check Dither in the
Export Preview, then enter a percentage value in the
Dither Amount field. Higher numbers increase
dithering and file size.
