Note: Right-click (Windows) or Control-click (Macintosh) a color in the palette to display a shortcut menu of edit options 
for the color.
Using websafe colors 
Websafe 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.
Fireworks has several methods of applying and using websafe colors.
To force all colors to be websafe colors:
Select Web 216 from the Indexed Palette pop-up menu in the Optimize panel.
To create an adaptive palette that favors websafe colors:
Select Web Adaptive from the Indexed Palette pop-up menu in the Optimize panel.
Non-websafe colors that are close to websafe colors are converted to the closest websafe color.
To force a color to its closest websafe equivalent:
1
Select a color in the Optimize panel color table.
2
 Click the Snap to Web Safe button.
If you save a Fireworks PNG, changing colors to websafe in the Optimize panel affects only the exported version of 
the image, not the actual image.
Saving palettes
You can save custom palettes as external palette files. You can use saved palettes with other Fireworks documents or 
in other applications that support external palette files, such as Adobe FreeHand, Adobe Flash, and Adobe 
Photoshop. Saved palette files have the .act extension.
To save a custom color palette: 
1
Select Save Palette from the Optimize panel Options menu.
2
Type a name for the palette and select a destination folder.
3
Click Save.
You can load the saved palette file into the Swatches panel or Optimize panel for use when exporting other 
documents.
Adjusting compression
You can compress GIF files to make them even smaller than usual by changing their loss setting. Higher loss settings 
can yield smaller files but lower image quality. A loss setting between 5 and 15 typically yields the best results.
