Regex colorization contrast is too low

[hrumhurum]

The following C# statement

var regex = new Regex(@"[\r\n]+(?<toc>(\s*-\s+(&\#x27B4;\s*)?\[(?<name>.+)]\((?<url>.+)\)\s*?([\r\n]|$)){2,})");

renders regex string with a low contrast. Please note how soft the colors are (especially yellow) on a white background.

Example:

I saw the same. I fixed it by using a different for "String - Escape character" in Tools/Options/Fonts-Colors.
