Hi Brian,
Thanks for posting your question in this community. From your description, you would like to resolve Color Display Problem in Excel. I love helping other users in the Community by sharing my experience with Microsoft products.
If you're experiencing issues with the fill color not displaying properly in Excel, there are a few things you can do to fix the problem.
First, make sure that the cells you're trying to fill are actually selected. If they're not, the fill color won't show up.
Next, check the fill color palette to see if the color you're trying to use is actually available. If it's not, you won't be able to use it.
If both of those things are set up correctly and you're still having trouble, try restarting Excel. Sometimes the program just needs a fresh start in order to work properly.
Please let me know if you have any more questions.
Have a great time ahead!
Regards,
Amaka
