Under warm 2700K interior light Transfusion is virtually unchanged; 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 4.49:1 and against black 4.68:1, so black 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.
#ffc7c2 · #ff8681 · #ea1833 · #be0023 · #820014 · #4a0007
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.
#f48000 · #f45503 · #ea1833 · #ca0057 · #a60069 · #820571
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.
#faab00 · #c79341 · #ea1833 · #b90824 · #890016 · #3f2800
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.
#00deed · #c9908c · #ea1833 · #9b3c3b · #732022 · #461011
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#daf9fc · #b6908d · #ea1833 · #556a6c · #411e1c · #000203
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 · #bccdcf · #8da1a3 · #0c282b · #000607 · #ea1833
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#dad8b3 · #39bef7 · #ea1833 · #8c5576 · #2a365e · #000930
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#d1fbff · #00b494 · #ea1833 · #006e98 · #003227 · #00060f
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#d7ffd4 · #41b644 · #ea1833 · #1752e7 · #00157b · #000200
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

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.
