Under warm 2700K interior light Laguna 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 ≈ 2.2), so it is a lighting-stable choice.

Against white it measures 2.84:1 and against black 7.38:1, so black text is the stronger pairing. That pairing passes WCAG AA for body text. Avoid white 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.
#dcf5ff · #7fd5f6 · #36a5c9 · #1688a9 · #00627c · #003d4f
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.
#75ceca · #52bbca · #36a5c9 · #448cbc · #4d75aa · #515e93
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.
#acb4da · #36a5c9 · #2a84a2 · #4c5599 · #00495d · #202445
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.
#b2e6fb · #a3bec9 · #36a5c9 · #ab5f3d · #325e6e · #223e48
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#fbefea · #36a5c9 · #6e7f86 · #504845 · #0f2127 · #060201
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.
#fcefe9 · #d6c7c1 · #ac9b95 · #38251d · #150401 · #36a5c9
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#e0deb9 · #88baab · #36a5c9 · #c32433 · #58384b · #031022
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#d2d6b0 · #de949f · #36a5c9 · #7b6653 · #593e40 · #051312
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#ffebf6 · #36a5c9 · #a16689 · #534c00 · #221f00 · #060002
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.
