On all of the Update Pages (Available Updates, Current Configuration, etc) the background color of the main title appears to be set to white. This should not be set to a fixed colour but should work like the Welcome Editor which uses JFaceColors.getBannerBackground(). This is unreadable when the display mode is set to High Contrast Black
Update pages use system color for list background and list foreground and should work well with user settings. I will test in other settings, but this is confusing.
Please point me at the code perhaps I can help with an accessibility review. The problem is white text on a gradient label - in high contrast black this unreadable due to the white text. You should use the list background colour for the label rather than the gradient.
OK, so that is the problem. Both PDE and Update use FormWidgetFactory to create its widgets, and it initializes like this: clientAreaColor = display.getSystemColor(SWT.COLOR_LIST_BACKGROUND); foregroundColor = display.getSystemColor(SWT.COLOR_LIST_FOREGROUND); Therefore, without the gradient itself, it would work, but since gradient is a fixed JPG, it does not work well. I should perhaps detect non-default background and drop the background. Also be advised that we were out of cycles to test on Linux so there may be a lot of issues there that we indent to fix soon.
In all other places we have decided to dump the gradient as a background altoghether and use the list background. This would be easier than some sort of detection and consistent with the rest of the UI. See the Welcome page for an example if you need it.

Fixed by dropping the banner if the background is not white (since it is a fixed gradient image that cannot track background changes and was designed for white background).
Forgot to change state.
