Under warm 2700K interior light Bullseye is virtually unchanged; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 0.6), so it is a lighting-stable choice.

Against white it measures 6.82:1 and against black 3.08:1, so white text is the stronger pairing. 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.
#ff9385 · #e65c4f · #b9030a · #8d0004 · #540001 · #220000
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.
#c16c00 · #bc4a00 · #b9030a · #990036 · #790043 · #5a0046
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.
#e1b465 · #cb9100 · #9e772f · #b9030a · #890003 · #5b0001
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.
#00ddf4 · #a3746d · #b9030a · #73261f · #4e0806 · #250000
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#ddf8fc · #ceaca7 · #6d8083 · #b9030a · #613f3a · #000304
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.
#e6f5f7 · #bccdd0 · #8ea1a4 · #0f2a2e · #00070a · #b9030a
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#d6f9ff · #00cce1 · #008c9b · #b9030a · #00535d · #080000
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#d4d7b1 · #74b8d6 · #5e9a8b · #b9030a · #465543 · #140b06
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#d7fedc · #61d078 · #4b6df1 · #b9030a · #243aa3 · #000200
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#A93128 · #99443B · #86514A
Its chroma is high enough to carry accents, calls to action, and focal moments; large fields of it will dominate a composition. In palettes it pairs most predictably with its tonal ramp and analogous neighbors; reserve the complementary hue for small, deliberate contrast.
