How Redsurrection behaves under real light

Under warm 2700K interior light Redsurrection 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.

Warm interior (2700K incandescent / warm LED): → #d90004 — ΔE 0.4, is virtually unchanged
Neutral LED (4000K task and retail lighting): → #dc0307 — ΔE 0.6, is virtually unchanged
Daylight (6500K standard daylight (reference)): → #d90b0b — ΔE 0.0, is virtually unchanged
Blue-sky shade (cool daylight (~10000K proxy)): → #da0c0c — ΔE 0.2, is virtually unchanged

Test Redsurrection in the color lighting simulator — sweep it through daylight, warm 2700K light, 4000K LED, and shade alongside the rest of your palette.

Contrast & accessibility

Against white it measures 5.25:1 and against black 4:1, so white text is the stronger pairing. That pairing passes WCAG AA for body text.

Colors that go with Redsurrection

Tonal

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.

#ffb4a9 · #ff6f5f · #d90b0b · #ac0002 · #710000 · #3b0000

Analogous

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.

#dc7c00 · #d85900 · #d90b0b · #b80041 · #970054 · #75005b

Shifted

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.

#e3a400 · #b58a36 · #d90b0b · #a80002 · #780000 · #312000

Contrast

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.

#00dcf5 · #bb857d · #d90b0b · #8d332a · #661711 · #3a0705

Quiet Support

The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.

#dbf8fd · #a9857f · #d90b0b · #4b5f62 · #3b1a15 · #000304

Bright Accent

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 · #8ea1a5 · #0f2a2e · #00070a · #d90b0b

Complementary

The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.

#d2d7b2 · #32aef6 · #b2708f · #d90b0b · #545a93 · #060930

Split-complementary

The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.

#bee0c7 · #6daecc · #5c9780 · #d90b0b · #515c87 · #1d040e

Triadic

Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.

#d4ffda · #0fab4b · #d90b0b · #2d41d6 · #0e0079 · #000200

Tetradic

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

Using Redsurrection

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.
