Spectrogram Palette Color Bar

This color bar runs down the left side of the Spectrogram Color Palette Dialog to show the current palette.

You can also use it to quickly find or enter Top or Bottom Index and RGB colors by eye. Just click on any portion of the color bar, then click the color square next to the Top or Bottom Index to transfer the color. If you just want to view the color without changing the palette, make sure that Lock Palette is active first.

See the Spectrogram Color Palette Dialog discussion for an example of how to use the color bar.
