Changing the display of the palette

You can show the individual color channels in color (rather than grayscale) in the Channels palette and specify the size of the thumbnails. Using thumbnails is the most convenient way of tracking channel contents; however, turning off the display of thumbnails can improve performance.

To show color channels in color:

1. Do one of the following:
• In Windows, choose Edit > Preferences > Display & Cursors.
• In Mac OS, choose Photoshop > Preferences > Display & Cursors.
2. Select Color Channels in Color, and click OK.

To resize or hide channel thumbnails:

1. Choose Palette Options from the Channels palette menu.
2. Select a display option:
• Click a thumbnail size. Smaller thumbnails reduce the space required by the palette--helpful when you're working on smaller monitors.
• Click None to turn off the display of thumbnails.
