Changing the Content Aware color for Eclipse Dark Theme - eclipse

So I downloaded the Eclipse Dark Theme and got the syntax highlighting worked out, but I am having issues when using content assist feature. The blue text on the dark background makes the text very hard to change, and I have tried digging around looking for settings to change this but I could not find any. Can someone give me some advice here?

eclipse color theme broken on Mac

eclipse color theme is failing to properly change background color for themes
dark theme background not dark enough
light theme background remains same shade of dark
The reason I'm really hoping to fix this issue is I prefer very dark backgrounds for higher contrast. It's easier on my eyes and reduces strain. Am hoping its either a setting/preferences issue or a quick hack to fix, but it'd be cool to be able to raise a bug with whoever is maintaining this plugin. Thanks!
EDIT: my post on eclipse subreddit got the solution. the DevStyle plugin is better maintained, has more useful theming/styling options, and is not buggy.

DBeaver Content Assist colors

I am having difficulty getting the Content assist colors right. With auto-completion, the first suggestion is always light color on light color. Here is what it looked like originally (Dracula Theme):
Changing the values of Content Assist Background/Foreground colors did not have any affect on the top suggestion. Here is a screenshot from after swapping the Content Assist Foreground and Background colors (Darkest Dark theme):
I have tried swapping every other practical color setting in Window->Preferences->General->Appearance->Colors and Fonts with no luck. The color scheme in the first image above is the popular Dracula theme that I manually set up setting by setting. Thinking I screwed something up in there, I scrapped all that work and switched to the Eclipse DevStyle theme Darkest Dark. Here, I was met with the same issue. After this, I switched everything to default settings where the color scheme is black font on white background. Everything is readable. Switching back to the Darkest Dark, the issue remains.
I have found similar questions regarding this, but their solutions are mostly for Linux (GTK specifically). This machine I am using is on Windows 7. I also have a laptop that runs DBeaver on Arch Linux and does not suffer from this problem. It seems this issue may be system dependent. I found one answer that suggested changing the message box settings for Windows may fix this, but my message box settings are currently black text on white background. Any help is greatly appreciated!
Most of the SWT widgets relay on the OS level theme. For example, it's known that using the Windows Classic theme at the OS level can cause oddities like this one. So just switching to a different theme can fix this issue.
maybe you have found the solution, just in case anyone is still searching...
we can change the color of "content assist", you can find in "Colors and fonts".

How to fix Dart hints background color

I just installed Dart, and the hints(of the autocomplete feature) had black text over dark grey background, nearly unredeable.
How can I fix this?
I already tried to change the theme of the IDE but that didn't work.

Eclipse dark theme arrow color

I was looking at this dark theme post and applied Moonrise theme on Eclipse Juno. I love everything it lays out except for the expandable arrow color. It's barely visible when my mouse isn't hovered. Does anyone know if this is possible to change?
As Spyros has mentioned, the author noted that the arrows color is impossible to change which is unfortunate.
Regardless, if you don't mind working under old graphic properties (yay!), the system arrow is replaced with a white box plus sign which makes everything visible. The drawback is, of course, the Windows 7 theme is gone. Found this by accident when trying to solve the performance issue: Look at Pyree's solution
I am afraid that is not possible due to the limitation of the css engine used to theme eclipse, according to the theme's author. (github)
