Website contrast tweak
Here's a way to improve the contrast of some of the pale gray elements on the website.
This only works in some web browsers, and it requires some setting up that takes a couple of minutes. For all the details see the document: Website Tweaks Overview
If you already have it all set up and you just want to install this tweak, here's the link: Install
If you want to customize the color after you've installed it, here's the settings page: Tweak Settings
For information about other tweaks, see the document: List of Tweaks
The main forum thread for all of this is: Web site tweaks

@RarelyCharlie I have never liked the white font on blue background in the listener's chat box. It would really be great if you could develop a tweak to change the colors. 
Yes, I'm pretty sure that could be done. I've added it to my list. What colours would you prefer? They'd be customizable, but I'm interested in knowing what you'd choose.

@RarelyCharlie Black font on a light gray background would work.
On reflection, the simplest solution was to extend this tweak with settings for the text and background colors. If you don't set them they remain the original white on dodgerblue, but now you can set them to black on lightgray or anything else you like.

@RarelyCharlie It seems a little complicated to make the change but I will give it a try. Thanks so much!
You're right in a way. For a simple thing like changing some colours this is a complicated method.
On the other hand, it's less geeky than any other method. This way you're not exposed to any computer languages or the internal structure of web pages.
It's also more powerful. I'm working on some things that go beyond just changing colours.
@Harry53
@RarelyCharlie Excellent!
