SelectionColor property

Color drawn over the selected text rectangles. Defaults to clHighlight (the Windows system selection color, conventionally blue) so the experience matches every other Windows text-editing surface.

Independent from HighlightColor, which colors search-result highlights (default clYellow). The two overlays use different colors and different paint passes — an active search highlight and a live drag-selection can be visible on the same page simultaneously without color conflict.

• Available since v1.36.0.
• Assigning the same color twice does NOT repaint — the setter checks the old value first.
• Changing the color with a non-empty selection on screen invalidates the view so the new color appears on the next paint.
