Under warm 2700K interior light Swimmer shifts subtly: loses intensity; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 2.1), so it is a lighting-stable choice.

Against white it measures 3.61:1 and against black 5.82:1, 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.
#b2e5ff · #68c1ea · #0a91bf · #00749a · #004f6a · #002c3e
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.
#56bcbf · #2ea7bf · #0a91bf · #3278b0 · #41619c · #464b84
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.
#b8bbff · #9d9fc9 · #0a91bf · #007197 · #005370 · #2d2d52
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.
#d8f2ff · #9cd2ec · #90abb9 · #0a91bf · #9a4c17 · #1e4c61
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#fcefe8 · #91a3ac · #0a91bf · #716864 · #1c2f38 · #030100
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.
#fbefe9 · #d6c9c1 · #ae9e96 · #3c2a20 · #1a0902 · #0a91bf
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#d5dab4 · #f8a04a · #0a91bf · #6467a1 · #503134 · #051213
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#d1dab5 · #d87c8d · #0a91bf · #68543f · #4f3734 · #041112
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#ffecf4 · #ce87a8 · #0a91bf · #6f6f00 · #2e2e00 · #0a0003
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.
