How Magma behaves under real light

Under warm 2700K interior light Magma is virtually unchanged; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 0.9), so it is a lighting-stable choice.

Warm interior (2700K incandescent / warm LED): → #ff4800 — ΔE 0.9, is virtually unchanged
Neutral LED (4000K task and retail lighting): → #ff4c00 — ΔE 0.3, is virtually unchanged
Daylight (6500K standard daylight (reference)): → #ff4e01 — ΔE 0.0, is virtually unchanged
Blue-sky shade (cool daylight (~10000K proxy)): → #ff4f04 — ΔE 0.1, is virtually unchanged

Test Magma 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 3.31:1 and against black 6.34:1, so black text is the stronger pairing. That pairing passes WCAG AA for body text.

Colors that go with Magma

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.

#ffe8e2 · #ffaf97 · #ff4e01 · #d23e00 · #982a00 · #621700

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.

#ffa308 · #fd7f00 · #ff4e01 · #e43949 · #c42c62 · #a1256f

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.

#d0b05b · #ff4e01 · #ce3d01 · #705700 · #721d00 · #312400

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.

#05d8ff · #ff4e01 · #976658 · #8b361c · #641a01 · #390900

Quiet Support

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

#ddf7ff · #ff4e01 · #927167 · #3a4d52 · #32130a · #000407

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.

#e7f5f9 · #bdcdd2 · #90a2a8 · #132c33 · #000a0f · #ff4e01

Complementary

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

#d7e8c5 · #42e1dc · #ff4e01 · #a66f8b · #37493b · #180e04

Split-complementary

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

#caddbb · #84afda · #ff4e01 · #43706c · #3c4940 · #170c03

Triadic

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

#d1ffe2 · #ff4e01 · #009158 · #391fbd · #160060 · #000501

Tetradic

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

Using Magma

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.
