Under warm 2700K interior light Dark Slate Blue shifts subtly: leans toward magenta; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 1.6), so it is a lighting-stable choice.

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.
#9b98d7 · #7670b7 · #483d8b · #34276f · #180547 · #030015
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.
#436fa4 · #44579a · #483d8b · #48286d · #41154e · #370330
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.
#c093b2 · #b4659e · #7f5974 · #483d8b · #2f2564 · #190a44
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.
#cfc963 · #8785af · #68677f · #483d8b · #2c2950 · #131127
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#f3f3e6 · #a7a6b8 · #65655c · #483d8b · #323243 · #010100
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.
#f3f3e7 · #cbcbbd · #a0a090 · #2a2916 · #090800 · #483d8b
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#dcd4af · #82c96d · #a779ab · #506857 · #483d8b · #030f24
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#f5f4d7 · #cca05d · #417423 · #483d8b · #482e00 · #000200
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#ffeee6 · #dd9472 · #007756 · #483d8b · #003f2c · #230600
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#48427E · #484571 · #494863
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.
