The iris look · Design System · v1.0
iris/os

One signal color. The intelligence layer for distributed solar has exactly one face — and this is it.

The signal color

iris 500 — the core

A high-luminance acid lime that reads as alive against deep ink. prism filters noise out of signal; this is the color of the signal that comes through. Click any value to copy.

iris ramp

Tints lift toward paper; shades sink toward ink. 500 is the only brand value — the rest are UI states (hover, borders, disabled, charts).

ink — the surface iris runs on

A warm graphite with a faint olive undertone so it sits under the lime, not against it. This is the OS. The platform that goes in front of capital lives here.

Pairings & legibility

Ask iris.

Lime on ink — the default

✓ 12.4:1 · AAA at any size

The primary expression. Lime is light, structure and brand on dark surfaces.

iris flagged it first.

Ink on lime — for fills

✓ 12.4:1 · AAA

Buttons, chips, highlights. Always near-black text on a lime fill — never white.

iris

Lime on paper — avoid for text

✕ 1.7:1 · fails text contrast

Lime is too luminous for type on white. Use it as a block/fill only, set type in ink.

iris

Ink on paper — light mode

✓ 16.8:1 · AAA

When a context demands white (capital decks, print), set type in ink and let lime accent.

Rules

Do

  • Treat #CFCC3F as the single corporate color. One stone.
  • Lead with lime on ink — that is the iris look.
  • Set type in ink-950 on any lime fill.
  • Use the ramp only for UI states, never as alternate brand colors.
  • Let the / in iris/os stay quiet — ink-600 weight.

Don't

  • No "powered by." facets are of iris/os, not bolted to it.
  • Don't set lime type on white — it fails legibility.
  • Don't introduce a second accent hue. The system is one color + ink.
  • Don't tint the lime warmer (gold) or cooler (green) — it drifts off-brand.
  • Never show iris-solar.ai in the mark. Plumbing only.

The architecture this color serves

iris

The AI you speak to. The named intelligence. Spoken + on the logo.

iris/os

The platform iris runs across. The OS for distributed solar. Goes in front of capital.

prism

The engine underneath. Filters noise out of signal — a facet of iris/os.

facets

What you switch on. Compliance first, then each lights up more value on the fleet.
