Viewing colors in a palette
The color table in the Optimize panel displays colors in the current preview when you are working in 8-bit color or less and lets you modify an image's palette. The color table updates automatically when you are in Preview mode. It appears empty if you are optimizing more than one slice at a time or if you are not optimizing in an 8-bit format such as GIF.
Various small symbols appear on some color swatches, indicating certain characteristics of individual colors, as follows:
|
Symbol |
Meaning |
|---|---|
|
|
The color has been edited, affecting only the exported document. This does not change the color in the source document. |
|
|
The color is locked. |
|
|
The color is transparent. |
|
|
The color is websafe. |
|
|
The color has multiple attributes. In this case, the color is websafe, is locked, and has been edited. |
If you edit the document, the color table may no longer show all the colors in the document. When this occurs, you should rebuild the color table. A Rebuild button appears at the bottom of the Optimize panel when you need to rebuild the color table.
To rebuild the color table to reflect edits in the document:
- Click Rebuild at the bottom of the Optimize panel.
When the table is rebuilt, the Rebuild button disappears, and the actual number of colors used in the image is displayed in its place.
To select a color:
- Click the color in the Optimize panel color table.
To select multiple colors:
- Control-click (Windows) or Command-click (Macintosh) the colors.
To select a range of colors:
- Click a color.
- Hold Shift and click the last color in the range you want to select.
To preview all the pixels in the document that contain a specific color:
- Click the Preview button at the upper left of the Document window.
- Click and hold on a swatch in the Optimize panel color table.
The pixels that contain the selected 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.
