Preview all the pixels in the document that contain a specific color
1
Click the Preview button at the upper left of the document window.
2
Click and hold on a color swatch in the Optimize panel color table.
The pixels that contain the selected color swatch temporarily change to another highlight color until you release the
mouse button.
Note:
When previewing pixels in the document using the 2-Up or 4-Up view, select a view other than the Original view.
Lock or unlock colors in a palette
You can lock individual colors so that you cannot remove or change them when changing palettes or when reducing
the number of colors in a palette. If you switch to another palette after colors have been locked, locked colors are added
to the new palette.
To toggle locking for a selected color swatch, click the Lock button
at the bottom of the Optimize panel, or
Right-click (Windows) or Control-click (Mac
OS) the color swatch, and select Lock Color.
To unlock all colors, select Unlock All Colors from the Optimize panel Options menu.
Edit colors in a palette
Editing a color replaces all instances of that color in images that are exported or saved as a bitmap. Except with bitmaps,
editing does not replace the color in the original image. If you are working with a bitmap, save a copy of the image as
a PNG file to retain an editable version of the original image.
1
Do one of the following to open the system color picker:
Select a color and click the Edit Color button
at the bottom of the Optimize panel.
Double-click a color in the color table.
2
Change the color.
Note:
Right-click (Windows) or Control-click (Mac OS) a color in the palette to display edit options.
Use websafe colors
Websafe colors
are colors that are common to both Mac OS and Windows platforms. These colors are not dithered
when viewed in a web browser on a computer display set to 256 colors. For a Fireworks PNG file, changing colors to
websafe in the Optimize panel affects only the exported version of the image, not the actual image.
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.
To Force a color to its closest websafe equivalent, select a color in the Optimize panel color table, and then click the
Snap To Web Safe button
.
