Unreadable default tooltip color choice

[Mailaender]

Bug report

What is the current behavior?

What is the expected or desired behavior?

A readable tooltip.

Please provide steps to reproduce:

Hover over a subsection. I don't know what triggers the warning as I can't read it.

Please describe your environment:

• TeXlipse version: 2.0.3
• Eclipse version: 4.9, 4.15, 4.18

Operating system:

• [ ] Windows
• [ ] macOS
• [x] Linux @openSUSE (KDE)

It seems that this color is not configurable in the preferences. This sounds like a good first bug (for me) to start contributing?

I guess that affects any Linux users...
