ColorOS 17

The current shadow hierarchy cannot be flexibly applied to all scenarios; in some cases it is difficult to find a shadow hierarchy with a high degree of compatibility, which can easily result in a disjointed appearance.

There is a significant disparity in the visual effects between the different shadow levels, which can create a disjointed experience for users.

The shadow effects on some layers are too heavy and lack sufficient diffusion; combined with the new materials, the texture lacks transparency, resulting in a less visually pleasing appearance.

Light striking a dense edge doesn't stop at it — it gathers. The stroke is that gathering: a bright rim where the material ends, strongest where the light lands most directly. A rim like this only happens on something solid and translucent, so the surface reads as a substance rather than a fill.

The rim is adaptive, not fixed. Its brightness is taken from the wallpaper behind it, so the edge holds the same separation against a white photograph and a black one — a single fixed value would have vanished into the first and shouted on the second. That is what makes it a rule rather than a look: the boundary of a panel is never in question, whatever the user has set behind it.

Light that gets into the material doesn't stay at the rim. It travels inward and gives out — bright just inside the edge, gone by the center. That falloff is what stops a large panel reading as a flat sheet of tint.

It also does the structural work, paired with the material blur behind it. The blur dissolves whatever sits behind the panel and buys the contrast; the glow lifts the interior so the result still reads as Luminous Sea Stone rather than a grey box. Content stays legible over anything, without the surface going dead.

Put polished stone on a table under a lamp and look underneath: there is a shadow, but there is also light — a pale bloom the stone returns to the surface, sitting on top of its own shadow.

Luminous Sea Stone does the same under every component. The shadow says the panel is above the surface; the returned light says it is above the surface and made of something that transmits. Shadow alone reads as a sticker. Shadow plus returned light reads as an object resting in space — which is what the elevation system is later built on.

Re-sorted every component in the system into five elevation tiers, so each one has a shadow defined for it rather than the nearest approximation. Tuned strength and material tier by tier — light enough to sit comfortably over long sessions, distinct enough that the hierarchy still reads at a glance.
