Inactive selection color too dark for Evolution

[Letterus]

What Happened?

Evolution is nicely styled when used with elementary. Selection color is fine, but the color for an inactive selection (default when starting up Evolution or when navigating through a folder tree) is too dark as it's almost black, rendering text unreadable.

Steps to Reproduce

1. Start Evolution with a mail account enabled.
2. Make the currently selected mail selection inactive, f.e. by clicking a folder in the left navigation pane.
3. Selected mail topic will be rendered dark, unreadable (see screenshot):
   

Expected Behavior

All text should be readable nicely all the time.
