how to remove unused font colors in spreadsheet

In calc I have several font colors that has been tried but not used. How can I remove them from the list?
Thanx!

Please remove tag math as your question is not related to the math formula editor. Use the retag link for that. I doubt tag text is relevant, too. Color would probably be a better choice.

MrHoggLegg,

You can find the answer in a previous post.

Which list do you refer to? One of the lists when you click the ‘Font Color’ icon in the Formatting Toolbar?

This isn’t an answer to the question, but a request for more information. Move it into a comment after the question and delete this “non answer”.
