At the Notes/Web tab, the user can choose from an IBMR LotusR NotesR color palette or a Web color palette. Note that the Notes tab becomes the Web tab only if the user has enabled "Use Web palette" (File - Preferences - User Preferences).
The RGB (Red, Green, Blue) value appears at the bottom of the palette for each color. If you are using the Notes palette, the name of the color also appears.
