Apple's elevation system uses layered surfaces with increasing background lightness in Dark Mode. Higher elevation means lighter surfaces, creating clear visual hierarchy.
Apple platforms use a layered surface system for visual hierarchy:
Unlike shadow-based systems, Apple relies primarily on background color differentiation and materials to convey depth.
Uses shadow for elevation perception
Uses tonal tint + subtle shadow

Base layer — root backgrounds, full-screen content. Pure white in light mode, true black (#000000) in dark mode on OLED.
1dp
First elevated surface — grouped table backgrounds, cards, secondary system background (#F2F2F7 light, #1C1C1E dark).
3dp
Popovers, sheets, tertiary system background (#FFFFFF light, #2C2C2E dark). Modals and floating panels.
6dp
Alerts, action sheets, highest-priority surfaces (#FFFFFF light, #3A3A3C dark). Requires immediate user attention.
8dp
Nested elevated content — menus on sheets, secondary modals (#FFFFFF light, #48484A dark).
12dp
Highest elevation — tooltips, contextual popovers, dragged items (#FFFFFF light, #545456 dark).
