Frequently Asked Questions
Why do Excel colors not change when I select a new color?
Windows Contrast themes, an Office theme, incorrect cell formatting, graphics driver problems, or an Excel add-in can prevent colors from displaying as expected. Start by selecting Start > Settings > Accessibility > Contrast themes > None.
How can I check whether the cell formatting is hiding the selected color?
Select the affected cell and open Home > Fill Color and Home > Font Color. Make sure the fill is not set to No Fill and the font color is not white or the same color as the background.
Does Excel Safe Mode help identify color and formatting problems?
Yes. Hold Ctrl while opening Excel to start Safe Mode. If colors work there, an add-in or customization is likely responsible; review add-ins under File > Options > Add-ins.
How do I repair Microsoft 365 when Excel formatting still looks wrong?
Open Control Panel > Programs and Features, select Microsoft 365, choose Change, and run Quick Repair. If that does not help, repeat the process with Online Repair.
