Hi Colleen,
You can change the worksheet tab color in Excel 2002 and Excel 2003,
but not in earlier versions.
- Select the sheets you want to color by holding down the CTRL key and clicking the tabs.
- Right-click the sheet tab and then click Tab Color.
- Click the color you want, and click OK.
I believe the normal reason to color tabs is to provide an organization to them. You can sort sheet tabs with a macro. You can
enhance your sorted arrangement by preceding the sheet tab with some less conspicuous small letters. i.e.
k.FunctKeys, k.ShortCutKeys See "sort sheet tabs" in
