Text color of the line and area measurement,

Text color of the line and area measurement,

I wanted to change the color of the text of line and area measurements but sounds not to work. It stays black.

Which text should I consider to change the text color of line and area measurements?

I think the color\size\font style of lines and text should be developed to let the end users choose their preferences.
