How Lionheart behaves under real light

Under warm 2700K interior light Lionheart is virtually unchanged; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 0.7), so it is a lighting-stable choice.

Warm interior (2700K incandescent / warm LED): → #cc1a1d — ΔE 0.7, is virtually unchanged
Neutral LED (4000K task and retail lighting): → #cf1f20 — ΔE 0.6, is virtually unchanged
Daylight (6500K standard daylight (reference)): → #cc2222 — ΔE 0.0, is virtually unchanged
Blue-sky shade (cool daylight (~10000K proxy)): → #cd2323 — ΔE 0.3, is virtually unchanged

Contrast & accessibility

Against white it measures 5.5:1 and against black 3.82:1, so white text is the stronger pairing. That pairing passes WCAG AA for body text.

Colors that go with Lionheart

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.

#ffada3 · #f96c5f · #cc2222 · #a5000c · #6a0004 · #350000

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.

#d87700 · #d45300 · #cc2222 · #af0b43 · #8f0152 · #6e0059

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.

#e09f00 · #af863f · #cc2222 · #9e0f13 · #710005 · #2e1d00

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.

#00ddf3 · #b3837c · #cc2222 · #84342d · #5e1814 · #330706

Quiet Support

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

#ddf8fc · #a2827d · #cc2222 · #495a5d · #381916 · #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 · #8ea1a4 · #0f2a2d · #000709 · #cc2222

Complementary

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

#d5d8b2 · #32ade1 · #a86f8a · #cc2222 · #515b8b · #030a31

Split-complementary

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

#d5faff · #00a18a · #cc2222 · #005d87 · #002b23 · #00050e

Triadic

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

#d8fedb · #31a44b · #cc2222 · #2743c5 · #090075 · #000200

Tetradic

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

Using Lionheart

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.
