Under warm 2700K interior light Tempest shifts subtly: leans toward purple; 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.

Against white it measures 3.8:1 and against black 5.53:1, so black text is the stronger pairing. That pairing passes WCAG AA for body text.
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.
#d2dbef · #aab3c9 · #79839b · #5f687e · #3e4659 · #202636
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.
#84aec8 · #7799be · #79839b · #6c6c99 · #665880 · #5c4666
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.
#d7b2e0 · #ac9ab1 · #79839b · #56658b · #3c496b · #3a2a3e
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.
#e3ebff · #d9c28c · #79839b · #5e6371 · #3b455c · #232936
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#f5f1ea · #9a9ea8 · #79839b · #6b6964 · #272b35 · #030200
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.
#edf2fc · #c4c9d4 · #79839b · #1c2231 · #01030e · #eabe4d
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#f8f1e1 · #ae9d74 · #79839b · #7b6633 · #382900 · #000008
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#f8f1e1 · #bc967a · #79839b · #666f3b · #422205 · #010100
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#ffedeb · #c1918a · #79839b · #4b7550 · #123418 · #050000
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

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.
