Under warm 2700K interior light Extraviolet shifts subtly: leans toward pink; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 1.4), so it is a lighting-stable choice.

Against white it measures 10.5:1 and against black 2:1, 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.
#b983d7 · #9658b6 · #661188 · #4f006c · #250036 · #05000c
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.
#5b59b5 · #623aa2 · #661188 · #5d005b · #4b0034 · #360016
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.
#f2a0b3 · #bb7fdb · #d0426f · #8b4a5a · #661188 · #44005e
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.
#94dc57 · #9774ab · #6f5b7a · #661188 · #3a164b · #190523
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#ebf6e5 · #ad9fb6 · #5a6156 · #661188 · #36283e · #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.
#eef4ea · #c4ccbf · #969f91 · #1c2615 · #010500 · #661188
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#c4ddbe · #d8b635 · #ae6da8 · #4a6248 · #661188 · #1d0512
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#c8f9f8 · #d6dc87 · #629783 · #4f5d4a · #661188 · #200516
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.

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.
