Spline — design system & UI screens

Design · 1 screen · 11 sections · spline.design

A near-black landing page where the hero is anchored by a cluster of colorful floating 3D primitives (cubes, spheres, glossy shapes) scattering outward behind centered serif/sans headline "The all-in-one platform for 3D and design." The signature element is the recurring use of rendered 3D scenes as content — a bright yellow "Hi" hand sculpture mid-page and a real editor viewport with manipulator gizmos — interleaved with dark bento feature cards, a multi-row grayscale logo wall, and a dark code/export panel showing cross-platform shipping to Web, iOS and Android.

Decoded design system

Spline's decoded design system: background #000000, text #FFFFFF, accent #3DDC84, link #3DDC84, primary #96B3FF; type scale h1 58px / h2 36px / body 16px; 4px spacing base; 16px base radius. The single interactive/action color is #333333 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#000000`
surface	`#0F0F0F`
border	`#262626`
text	`#FFFFFF`
text_muted	`#9E9E9E`
primary	`#96B3FF`
accent	`#3DDC84`
link	`#3DDC84`
secondary	`#915EFF`
button_bg	`#333333`
button_text	`#FFFFFF`

Using these colors

Action color #333333 — the single interactive color; only on things you click or must notice, never large fills.
accent, link are all #3DDC84 — one role, not several (the action color).
accent #3DDC84 — accent for emphasis — keep it rare on the page.
primary #96B3FF — a brand color — but the call-to-action uses #333333, not this.
secondary #915EFF — optional secondary accent — LOW decode confidence; use rarely (a status color or a single decorative moment) or omit it entirely. Prefer one accent unless the reference clearly shows two.
