For the standard backdrops (WINDOW and PARTIAL) reduced transparency doesn't matter much. In normal operation the window backdrop will track the window's color scheme (LIGHT or DARK). The translucency effect might go away but the overall background color will be the same. The real complication comes from the other accessibility settings; on Windows the backdrop will also respond to the high contrast themes. The most appropriate way to draw on a standard backdrop is to make no assumptions about what color it's going to display and consult Platform Preferences for appropriate foreground colors. For the platform-specific backdrops anything goes. Most of them will follow the window's color scheme, some will not. The clear glass effect on macOS is always light colored when "reduced transparency" is off and ignores the color scheme. But if "reduced transparency" is on it starts tracking the color scheme. Most of the other effects on macOS track the window's color scheme and platform accessibility settings. ------------- PR Comment: https://git.openjdk.org/jfx/pull/2048#issuecomment-4493398809
