Under warm 2700K interior light 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 ≈ 1.2), so it is a lighting-stable choice.

Against white it measures 8.98:1 and against black 2.34:1, 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.
#b58fb8 · #916795 · #66386a · #4b214e · #28032b · #07000a
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.
#6f6697 · #6b4f82 · #66386a · #5a274b · #4c182e · #3b0a15
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.
#c39798 · #b96c71 · #825d5f · #66386a · #46214a · #2b092e
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.
#9dd59c · #9b829c · #746675 · #66386a · #3d263f · #1d101e
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#edf4ec · #afa5b0 · #626762 · #66386a · #3b313c · #000100
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.
#ecf5eb · #c2ccc1 · #94a093 · #182718 · #000500 · #66386a
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#f6f0ca · #b4ee89 · #b870a5 · #4e6653 · #66386a · #0e0729
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#e7f7e6 · #a8af76 · #007761 · #66386a · #353900 · #000201
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#fbf1dc · #c0a56f · #00737c · #66386a · #003d42 · #0e0600
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#613D64 · #5C425E · #564657
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.
