White `#FFFFFF`

White (#FFFFFF) is a near-white neutral with an OKLCH hue of 90°, lightness 1 and chroma 0. In practice it behaves as a background color — quiet over large surfaces.

How White behaves under real light

Under warm 2700K interior light White shifts subtly: takes on a yellow cast, reads darker, gains intensity; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 2.3), so it is a lighting-stable choice.

Warm interior (2700K incandescent / warm LED): → #fff9ee — ΔE 2.3, shifts subtly: takes on a yellow cast, reads darker, gains intensity
Neutral LED (4000K task and retail lighting): → #fffffa — ΔE 0.7, is virtually unchanged
Daylight (6500K standard daylight (reference)): → #ffffff — ΔE 0.0, is virtually unchanged
North light / shade (~7500K diffuse blue-sky light): → #ffffff — ΔE 0.0, is virtually unchanged

Contrast & accessibility

Against white it measures 1:1 and against black 21:1, so black text is the stronger pairing. That pairing passes WCAG AA for body text. Avoid white text on this color entirely.

Palettes built from White

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.

#ffffff · #c9c9c9 · #a2a2a2 · #7c7c7c · #595959 · #383838

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.

#ffffff · #ffe7c9 · #fbcdac · #eab7a4 · #d6a39d · #c09096

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.

#ffffff · #b1c4ae · #ae9d71 · #668c62 · #71623a · #3b4e39

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.

#ffffff · #e0daca · #c2b79a · #9e957b · #495784 · #3d3728

Quiet Support

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

#ffffff · #dee1e8 · #a19d93 · #5d5f64 · #2a271d · #010102

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.

#ffffff · #c9c9c9 · #9c9c9c · #222222 · #030303 · #e7c04d

Complementary

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

#ffffff · #dbe1f1 · #8f9cc4 · #4e5d8a · #1b2446 · #0b0500

Split-complementary

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

#ffffff · #dbe1f1 · #7ca3c0 · #655583 · #002a43 · #020006

Triadic

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

#ffffff · #d1e6ea · #71a8b2 · #774f73 · #381a36 · #000305

Tetradic

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

#ffffff · #d2e6e2 · #74aa9f · #4e5d8a · #3f1826 · #000008

Using White

Its high lightness and low chroma make it a natural background or large-surface color.
