Excel does not give you as much control over colors as Word.
One option to consider is to create a custom "theme"
Set a Default Theme in Excel
When you create a new Excel workbook, you’ll notice that it always reverts to the Office theme color by default.
However, in some cases, you might have a set of defined theme colors that you want to use every time you create a new workbook.
Instead of changing the colors of all the elements in the workbook one by one, Excel allows you to store a custom theme that you can apply with a few clicks.
Unfortunately, unlike Microsoft Word, Microsoft Excel does not have an option to set a custom theme as the default theme.
Luckily, there is a workaround to do this on Microsoft Excel. To do this, save an empty Excel sheet containing the desired theme colors as an Excel template inside the Excel Start folder.

No, this article does not answer your question.
This old article has a lot of useful information about using colors in Excel. Unfortunately it was written for Excel 2003, so some of the tips are no longer useful, but most still are.
