Under warm 2700K interior light Royal Plum shifts subtly: leans toward pink; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 1), so it is a lighting-stable choice.

Against white it measures 8.46:1 and against black 2.48:1, 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.
#b596b0 · #916f8c · #654161 · #4a2a47 · #280c26 · #090008
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.
#8f636e · #7c5068 · #654161 · #4d3359 · #34284c · #1e1d3c
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.
#c09e9b · #b27774 · #806361 · #654161 · #472844 · #2c1029
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.
#a1d2ab · #9d879a · #766a74 · #654161 · #3f2b3c · #1f141e
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#edf4ee · #b0a7af · #656a66 · #654161 · #3d343c · #010201
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.
#fdecfa · #d5c2d2 · #654161 · #31182f · #0c000c · #d870cf
The same quiet ground carrying one bright gold voice — the high-energy pairing a cool or muted anchor cannot reach through its own temperature.
#fdecfa · #d5c2d2 · #654161 · #31182f · #0c000c · #e0c34d
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#ddd7b1 · #9cbc7b · #c3759f · #58745d · #654161 · #1e050e
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#e8f6ea · #a5b186 · #2d776b · #654161 · #333c13 · #000201
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#f7f2e1 · #b9aa7f · #287481 · #654161 · #004049 · #0b0500
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#61445D · #5C485A · #584B56
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.
