Is your workbook shared, if it is shared the
coloured tabs will be grayed out and not available
for compatibility reasons.

The 'Tab Color' menu item is disabled on the Format menu and also when I
right click the tab name. There are no disabled items (Help-About
Microsoft
Office Excel--Disabled Items).
Help! Very frustrating (there is already a colored tab in this
spreadsheet
so at one time I was able to access the menu item 'tab color.')
Thanks.
