How Horizon behaves under real light

Under warm 2700K interior light Horizon shifts subtly: leans toward blue-green; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 1.6), so it is a lighting-stable choice.

Test Horizon in the color lighting simulator — sweep it through daylight, warm 2700K light, 4000K LED, and shade alongside the rest of your palette.

Contrast & accessibility

Against white it measures 3.82:1 and against black 5.49:1, so black text is the stronger pairing. That pairing passes WCAG AA for body text.

Colors that go with Horizon

Tonal

One color explored: close hues with real lightness and chroma structure, so the palette is the anchor through value rather than a set of colors.

#c2dee8 · #97b7c2 · #648894 · #4b6d78 · #2c4a53 · #0e2931

Analogous

The anchor's neighbours on the wheel — everything shares an undertone, so the chord carries color without anything having to be muted to get along.

Shifted

The mid-gap pairing — sage and mustard, terracotta and olive. A foil rotated 40–65° toward warm or cool: too far to be kin, too near to argue, carried by temperature and a deliberate value offset.

#aebdf0 · #979fb8 · #648894 · #366d7e · #1c505f · #282d44

Contrast

One deliberately opposed voice — a single restrained counterpoint across the wheel, or temperature against temperature where the anchor is too muted to carry a loud opposite.

#d7eef6 · #a9ccd8 · #94a6ad · #648894 · #865240 · #2c4851

Quiet Support

The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.

Bright Accent

This color as a ground rather than a subject — its own restraint held across a narrow value band, carrying one saturated voice from the opposite temperature.

Gold Accent

The same quiet ground carrying one bright gold voice — the high-energy pairing a cool or muted anchor cannot reach through its own temperature.

Complementary

The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.

#d3d9b3 · #dba970 · #648894 · #545e82 · #4a2d2b · #051312

Split-complementary

The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.

#ffeee7 · #bf8e94 · #648894 · #835f34 · #451b23 · #100500

Triadic

Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.

#fdecf6 · #b78ea8 · #648894 · #716832 · #322b00 · #040002

Tetradic

Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

Using Horizon

Its moderate chroma lets it work in mid-size areas — upholstery, secondary UI surfaces, editorial blocks — without overwhelming neighbors. In palettes it pairs most predictably with its tonal ramp and analogous neighbors; reserve the complementary hue for small, deliberate contrast.
