Under warm 2700K interior light Teal Blue shifts subtly: leans toward blue-green, loses intensity; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 1.8), so it is a lighting-stable choice.

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.
#94ddf0 · #61b7cb · #01889f · #006b7d · #004653 · #00232b
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.
#60aea2 · #389ca0 · #01889f · #1d7194 · #2a5b85 · #304672
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.
#99b5f8 · #8997b8 · #01889f · #00687b · #004a58 · #1c2744
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.
#c7e7ef · #94c7d3 · #86a0a6 · #01889f · #894230 · #16434d
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#fbefeb · #87989c · #01889f · #665d5b · #192a2f · #040101
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.
#fceeeb · #d5c5c1 · #aa9893 · #321e19 · #0e0100 · #01889f
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#d4d7b2 · #e5922e · #01889f · #50649b · #4a2d31 · #061511
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#d2d6b0 · #d2638d · #01889f · #7d5962 · #61493b · #041210
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#ffebfa · #b481a8 · #01889f · #715e00 · #302700 · #050003
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#378597 · #4F838F · #617F87
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.
