Under warm 2700K interior light Dancing Sea shifts subtly: leans toward purple, loses intensity; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 1.7), so it is a lighting-stable choice.

Against white it measures 8.37:1 and against black 2.51:1, 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.
#89afe3 · #5f88c2 · #3562a2 · #1c4d8f · #001f4c · #000420
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.
#1d7b99 · #0f6596 · #1c4d8f · #2c3678 · #2f225f · #2b0f43
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.
#b29bc6 · #9d72bf · #756185 · #1c4d8f · #093267 · #001942
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.
#eeb862 · #768fb3 · #606e83 · #1c4d8f · #1a3253 · #0a172a
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#f8f1e5 · #a1abba · #6c675f · #1c4d8f · #2d3746 · #020100
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.
#f8f1e6 · #d4cbc0 · #aca295 · #3c3120 · #1b1001 · #1c4d8f
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#ffefd9 · #cca261 · #8a5e00 · #1c4d8f · #4b3100 · #00031b
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#ffefd9 · #dd9774 · #6f6b00 · #1c4d8f · #5c2300 · #040300
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#ffeded · #e09194 · #43772b · #1c4d8f · #184200 · #130001
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#2A4E82 · #354F74 · #3F4F67
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.
