Under warm 2700K interior light Myrtle shifts subtly: leans toward yellow; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 0.8), so it is a lighting-stable choice.

Against white it measures 11.27:1 and against black 1.86:1, 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.
#89a286 · #617e5e · #3c5b39 · #21421e · #001a00 · #000200
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.
#3e7571 · #2d6556 · #23543a · #21421e · #243207 · #222200
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.
#8eb5b4 · #799775 · #307d7d · #3a5a5a · #21421e · #0b2709
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.
#afbdae · #a983ae · #4f5a4e · #21421e · #122310 · #010900
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#f5f0f6 · #b4bbb3 · #858186 · #4b534a · #21421e · #252126
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.
#f6eff6 · #cec6ce · #a199a2 · #291f2a · #070208 · #21421e
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#dbd7b1 · #acbf88 · #8950d7 · #3e5088 · #21421e · #04082d
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#f9edfb · #b9b2dd · #a67087 · #514a71 · #21421e · #301b24
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.

Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

As a deep tone it works for grounding elements — text, outlines, and shadowed surfaces — rather than open fields. In palettes it pairs most predictably with its tonal ramp and analogous neighbors; reserve the complementary hue for small, deliberate contrast.
