Under warm 2700K interior light Ruby Red is virtually unchanged; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 0.5), so it is a lighting-stable choice.
#9b091a — ΔE 0.5, is virtually unchanged#9d0e1d — ΔE 0.4, is virtually unchanged#9b111e — ΔE 0.0, is virtually unchanged#9c121f — ΔE 0.3, is virtually unchangedAgainst white it measures 8.42:1 and against black 2.49:1, so white text is the stronger pairing. That pairing passes WCAG AA for body text. Avoid black text on this color entirely.
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.
#ea837d · #c85653 · #9b111e · #73000f · #3e0003 · #110000
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.
#ad5d0f · #a73c0b · #9b111e · #7f0032 · #61003a · #440039
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.
#cda466 · #bb7f00 · #8b6832 · #9b111e · #70000e · #440004
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.
#00deee · #c17e79 · #8e6763 · #9b111e · #5d1d1d · #310d0d
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#e0f7f9 · #c1a5a2 · #607071 · #9b111e · #4e3330 · #000202
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.
#e6f5f7 · #bccdcf · #8ea2a4 · #0f2a2d · #000709 · #9b111e
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#d2fbff · #00c3d2 · #007b85 · #9b111e · #00444a · #080000
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#d5dbb6 · #7bb1db · #568b81 · #9b111e · #394739 · #190a03
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#defbdd · #74c375 · #3964cd · #9b111e · #123284 · #000200
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

Its chroma is high enough to carry accents, calls to action, and focal moments; large fields of it will dominate a composition. In palettes it pairs most predictably with its tonal ramp and analogous neighbors; reserve the complementary hue for small, deliberate contrast.
