Under warm 2700K interior light Rouge is virtually unchanged; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 0.7), so it is a lighting-stable choice.

Against white it measures 7.3:1 and against black 2.88:1, 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.
#fa8a93 · #d85b6a · #ab1239 · #820027 · #4b0012 · #1c0002
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.
#c16027 · #b93e2b · #ab1239 · #8d0249 · #6d0050 · #4e004f
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.
#e1aa6f · #d38300 · #9d6f3a · #ab1239 · #7f0025 · #520015
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.
#00e0e1 · #d0868b · #9a7072 · #ab1239 · #6a242d · #3d1419
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#dff8f7 · #c8a9ab · #6a7b7a · #ab1239 · #593b3d · #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.
#e6f5f5 · #bccdcd · #8ca0a0 · #0b2727 · #000505 · #ab1239
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#c8fefd · #00cbcd · #008889 · #ab1239 · #004f50 · #180002
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#c5dfc0 · #74bf8f · #5b93a2 · #ab1239 · #3c495f · #1e0514
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#e2fbd6 · #87c765 · #1374de · #ab1239 · #004288 · #000200
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#9D3141 · #8E4149 · #7E4D50
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.
