Under warm 2700K interior light Cape Verde shifts subtly: leans toward green; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 1.2), so it is a lighting-stable choice.

Against white it measures 8.7:1 and against black 2.41:1, 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.
#74a59f · #48817a · #01554f · #003a36 · #001916 · #000201
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.
#417381 · #20646a · #01554f · #014736 · #0d3820 · #13290b
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.
#89a4b7 · #5588aa · #516878 · #01554f · #003833 · #001d1a
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.
#b47a85 · #596c69 · #01554f · #0f3330 · #001715 · #000202
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#f9eff0 · #9daaa8 · #666061 · #01554f · #273533 · #020101
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.
#f9eff0 · #d2c6c7 · #a6989a · #2e1e21 · #0a0103 · #01554f
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#d4dcb7 · #93ce95 · #e92fb4 · #6f5688 · #01554f · #1a0723
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#ffecef · #c099b5 · #875243 · #01554f · #45243d · #050000
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#f6eefe · #b09ec5 · #7f5930 · #01554f · #472a06 · #020005
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.
