How Doctor behaves under real light

Under warm 2700K interior light Doctor shifts subtly: takes on a orange cast, gains intensity; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 2.2), so it is a lighting-stable choice.

Warm interior (2700K incandescent / warm LED): → #fff3e9 — ΔE 2.2, shifts subtly: takes on a orange cast, gains intensity
Neutral LED (4000K task and retail lighting): → #fffaf4 — ΔE 1.1, shifts only faintly, with no single dominant change
Daylight (6500K standard daylight (reference)): → #f9f9f9 — ΔE 0.0, is virtually unchanged
Blue-sky shade (cool daylight (~10000K proxy)): → #f9fafc — ΔE 0.4, is virtually unchanged

Test Doctor 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 1.05:1 and against black 19.95:1, so black text is the stronger pairing. That pairing passes WCAG AA for body text. Avoid white text on this color entirely.

Colors that go with Doctor

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.

#f9f9f9 · #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.

#f9f9f9 · #ffe0b8 · #f5c7a6 · #e4b19e · #d09d97 · #ba8a91

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.

#f9f9f9 · #abbfa8 · #a8986b · #61865d · #6b5d35 · #364934

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.

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.

Complementary

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

#f9f9f9 · #d5dbeb · #8b98bf · #4c5a87 · #1a2345 · #0b0500

Split-complementary

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

#f9f9f9 · #d5dbeb · #789fbb · #635381 · #002941 · #020006

Triadic

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

Tetradic

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