#### Steps to reproduce: <!-- Describe what you did (step-by-step) so we can reproduce: --> - open Inkscape - make sure using the dark theme (in my case is the default one) #### What happened? Some icons are hard to be seen, like for instance: - "Create and edit text objects (F8)" - "Snap text anchors and baselines" - "Snap to grids" - "Snap to guides"   Others seem to be the same design or hard to differentiate, such as: - "Enable snapping (%)" - "Snap bounding boxes" - "Snap nodes, paths, and handles" - "Snap other points (centers, guide origins, gradient handles, etc.)"  And others are clearly designed for a light theme, their background is white which clearly doesn't fit with a dark theme at all, like these two: - "Select all objects or all nodes (Ctrl+A)" - "Select all objects in all visible and unlocked layers (Ctrl+Alt+A)"  #### What should have happened? A dark theme requires a set of icons whose colors are light enough to distinguish them easily. #### Inkscape Version and Operating System: - Inkscape Version: 1.0alpha (inkscape@9dee831c6779be43d9098c3040d9b5f94ecfd43a, 2019-01-15) <!-- (run inkscape -V or copy from Help → About Inkscape, top right) --> - Operating System: Linux Debian 9.7 - Operating System version: Linux Debian 9.7 // 4.9.0-8-amd64 inkscape#1 SMP Debian 4.9.130-2 (2018-10-27) x86_64 GNU/Linux
