How Mario behaves under real light

Under warm 2700K interior light Mario 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): → #e40007 — ΔE 0.3, is virtually unchanged
Neutral LED (4000K task and retail lighting): → #e7000b — ΔE 0.6, is virtually unchanged
Daylight (6500K standard daylight (reference)): → #e4000f — ΔE 0.0, is virtually unchanged
Blue-sky shade (cool daylight (~10000K proxy)): → #e50210 — ΔE 0.2, is virtually unchanged

Test Mario 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 4.88:1 and against black 4.31:1, so white text is the stronger pairing. That pairing passes WCAG AA for body text.

Colors that go with Mario

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.

#ffbeb4 · #ff7b6c · #e4000f · #b50008 · #790003 · #430000

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.

#e58000 · #e25b00 · #e4000f · #c10047 · #9f005a · #7d0063

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.

#eca900 · #bd8f36 · #e4000f · #b10008 · #810004 · #372400

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.

#00ddf4 · #c38a82 · #e4000f · #95362e · #6d1a15 · #400b08

Quiet Support

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

#d9f9fe · #b08a84 · #e4000f · #4f6467 · #3f1b17 · #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 · #0f2a2e · #00070a · #e4000f

Complementary

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

#d3dab4 · #37c2a9 · #e4000f · #825277 · #2b3a2a · #1b0d04

Split-complementary

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

#d6f9ff · #00ad95 · #e4000f · #006796 · #002f27 · #00050f

Triadic

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

#d4ffd9 · #10b24a · #e4000f · #2c45e2 · #0d007f · #000200

Tetradic

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

#edf9c3 · #8da000 · #e4000f · #006d79 · #340065 · #000304

Using Mario

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.
