Description:
In a file saved as a MS word file, 2007-2019 format (using LibreOffice Writer) --- when I make (using Highlight Color icon) background of some text as tan colour, then upon closing the file and opening it, I find that the background has changed from tan to yellow 

Version of my LibreWriter is  6.2.4.2 (x64)

CPU of my laptop is AMD A8-7410

OS is Windows 10 Home Single Language 64-bit


Steps to Reproduce:
1.Select some text (letters / digits) in a MS word file, while using Libre Writer
2.Using Highlight Colour icon, make background of the text as 'tan' colour (of 'html' pallete)
3.Close the file
4. Re-open the file using Libre Writer

Actual Results:
The highlight (background) colour of that text, instead of being 'tan', is a bright yellow

Expected Results:
The highlight (background) colour of that text, should have remained as 'tan'.
