Under warm 2700K interior light Glacier shifts subtly: leans toward blue-green, loses intensity; in north-facing or shaded light it shifts subtly: leans toward blue. Overall drift across common illuminants is small (max ΔE ≈ 2), so it is a lighting-stable choice.

Against white it measures 2.38:1 and against black 8.84:1, 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.
#dbf8ff · #9fd3e0 · #78b1bf · #538692 · #33616c · #143e48
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.
#a2dad0 · #85c7c9 · #78b1bf · #669cb7 · #6286a7 · #5e7193
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.
#78b1bf · #7e889f · #3a7482 · #3c4d78 · #003c47 · #131b2f
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.
#cff5ff · #bacdd2 · #78b1bf · #ad7566 · #4c6b72 · #374a4f
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#f9efed · #78b1bf · #818d91 · #585251 · #182427 · #030101
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.
#e1f6fc · #b6cfd5 · #78b1bf · #002b34 · #00070b · #eb5d3b
The same quiet ground carrying one bright gold voice — the high-energy pairing a cool or muted anchor cannot reach through its own temperature.
#e1f6fc · #b6cfd5 · #78b1bf · #002b34 · #00070b · #ecbd4d
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#d5dbb6 · #78b1bf · #9f6639 · #4a5a7c · #462b30 · #051210
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#ffede9 · #78b1bf · #ab7c86 · #704a23 · #3a131e · #120500
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#fcecf8 · #78b1bf · #a27e9a · #61531c · #2a2100 · #030003
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#83AFBA · #8EADB5 · #97AAAF
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.
