Plum vs Aubergine: The Real Difference
The plum vs aubergine question comes up because both are deep, sophisticated purples that read as luxurious and a little dramatic. The difference is one of depth and warmth. Plum is a richer, brighter purple that clearly shows its red-pink heritage, the color of the ripe fruit’s flesh. Aubergine is far darker and more muted, sitting so close to black that it often functions as a moody neutral, named for the deep skin of the eggplant. Knowing which is which keeps your fashion, interiors, and branding from looking either flat and murky or unexpectedly bright.
Both colors live in the purple family, but they occupy very different positions on the depth scale. Plum keeps more saturation and lightness, so its purple stays vivid and jewel-toned. Aubergine carries a heavy load of black and a touch of brown, which drags it toward near-black and gives it a quieter, more grounded character. Below we define each color, give accurate hex codes, and explain exactly when to reach for one over the other.
Plum
Plum sits around #8E4585 in its classic form, a medium-dark purple with clear richness and warmth. It is named after the fruit, and like ripe plum flesh it carries a noticeable red-pink glow beneath the purple. This warmth keeps it vivid and jewel-like rather than muddy, and it is what separates plum from cooler, greyer purples.
The undertone of plum is warm, leaning toward red and magenta. It is unmistakably purple, but the red lean gives it energy and a slightly romantic, opulent feel. Plum reads as a true color rather than a near-neutral, holding enough saturation to feel rich and expressive. Think of velvet, jewel tones, and autumn florals.
In usage, plum excels wherever you want a luxurious purple that still has life and color. It is popular in fashion, beauty and cosmetics branding, autumn and winter palettes, and elegant event design. Because it is warm and saturated, it pairs beautifully with gold, blush, soft pink, and warm greys. It makes a strong feature color, adding richness and drama without going so dark that it loses its purple identity. Designers reach for plum when they want a purple that feels regal and inviting at the same time.
Aubergine
Aubergine is a much deeper, more muted purple, sitting around #3D2438 and often pushed toward #4B2E43 or darker. Named for the deep skin of the eggplant, it is so dark that it frequently reads as near-black, only revealing its purple-brown character in good light. This near-black depth is its signature trait.
The undertone of aubergine is cool and complex, blending purple with a noticeable brown and grey component. That brown lean is what keeps it from looking like a simple dark purple; it gives aubergine a moody, earthy sophistication. Where plum glows, aubergine smolders. It carries enough black to feel grounded and serious, making it one of the most refined and versatile dark tones in the purple family.
Aubergine shines wherever you want the drama of a deep purple with the practicality of a near-neutral. It is a favorite for moody interiors, luxury fashion, premium packaging, and sophisticated branding. Because it is so dark and slightly brown, it behaves almost like a colored charcoal, anchoring a palette while feeling richer than plain black. It pairs elegantly with brass and gold, blush, sage green, and warm creams, where its depth provides contrast and gravity without harshness.
Key Differences
| Color | Hex | Undertone | Best for |
|---|---|---|---|
| Plum | #8E4585 | Warm, red-pink lean, clearly purple | Fashion, beauty branding, jewel-tone palettes, elegant events |
| Aubergine | #3D2438 | Cool, brown-grey purple, near-black | Moody interiors, luxury packaging, sophisticated dark anchors |
The fastest way to tell them apart is depth and warmth. If the purple is clearly purple with a warm, jewel-like red-pink glow, it is plum. If it is so dark it nearly passes for black and carries a moody brown lean, it is aubergine. Side by side, plum looks vivid and regal while aubergine looks deep, earthy, and grounded.
Hex Codes & How to Use Each
For plum, build around #8E4585, which is RGB 142, 69, 133. Notice how the red and blue values dominate over green, producing that warm, magenta-leaning richness. For a deeper plum, drop toward #6E3866; for a brighter, more fruit-forward version, lift toward #A04C95. Use plum as a saturated feature color against warm neutrals like blush (#F2D7D9), soft cream, and brushed gold. It works beautifully as a hero background, an accent in beauty branding, or a velvet-textured element. Keep supporting tones warm to preserve its jewel-like glow.
For aubergine, anchor on #3D2438, RGB 61, 36, 56, or go deeper toward #2E1B2A for a near-black luxury feel. Because aubergine is so dark, use it as a structural anchor: large moody fields, premium packaging, feature walls, and navigation bars all benefit from its weight. It pairs cleanly with gold and brass for contrast, with blush and sage for softness, and with cream for an upscale, layered look. Unlike plum, aubergine does not need to be vivid; let it sit as the deepest tone in your palette and let warmer or lighter colors provide the visible glow above it.
A practical tip: plum and aubergine make an excellent tonal pairing, with aubergine as the deep anchor and plum as the brighter mid-tone, building depth within the purple family. For a parallel comparison where depth and undertone separate two close shades in a warmer family, see our guide on chocolate vs espresso.
Lighting matters more with these two purples than with most colors, so test your hex codes in context before committing. Aubergine in particular shifts dramatically: under warm incandescent light it reveals more of its red and brown warmth and can look almost like a deep wine, while under cool daylight or LED it pulls toward a grey-purple charcoal. Plum is more stable but still reacts to its neighbors. Place plum next to a warm cream and its magenta glow intensifies; place the same plum next to a cool grey and it can suddenly read browner and more muted. Always view a swatch at full scale and under the actual lighting of the final environment, whether that is a screen, a printed page, or a painted wall, because a small chip on a bright monitor rarely predicts how the color behaves across a large surface.
When to Choose Each
Choose plum when you want a rich, expressive purple that still reads vividly as color. It is the right call for beauty and cosmetics branding, autumn and winter fashion, elegant event design, and any palette that wants warmth and opulence. Its red-pink glow makes it feel regal and inviting rather than severe, and it works especially well when you want a jewel tone that adds drama without disappearing into darkness. If you want a purple with visible life and warmth, plum is the pick.
Choose aubergine when you want depth, sophistication, and a refined alternative to black. It is ideal for moody interiors, luxury packaging, premium fashion, and minimalist branding that wants richness without losing seriousness. Aubergine provides gravity and structure to a palette while feeling warmer and more interesting than plain charcoal. When in doubt, ask whether the design should feel like a glowing jewel (plum) or a deep, moody shadow (aubergine). For another subtle two-tone study, see our breakdown of orchid vs lavender.
Frequently Asked Questions
Is aubergine just a darker plum?
Not quite. Aubergine is darker, but it is also cooler and carries a brown-grey component that plum does not. Plum keeps a warm, jewel-like red-pink glow and clearly reads as purple, while aubergine pushes toward near-black with a moody, earthy undertone. So aubergine is darker and more muted, not simply a deeper version of plum’s vivid warmth.
What undertone does plum have?
Plum has a warm undertone that leans red and magenta, the same glow you see in ripe plum fruit. That red-pink lean is what keeps it vivid and jewel-like rather than muddy. It pairs naturally with gold, blush, and warm cream, and it reads as a true, expressive purple rather than a near-neutral, which gives it a regal, opulent feel.
Can aubergine be used like a neutral?
Yes. Because aubergine sits so close to black and carries a brown lean, it functions as a sophisticated colored neutral, much like charcoal but richer and warmer. It anchors a palette, adds weight to large fields and feature walls, and pairs cleanly with gold, cream, or blush. Many designers use aubergine instead of black for a deeper, more interesting result.
Which purple is better for a feature wall?
It depends on the mood. Aubergine is the popular choice for dramatic, moody feature walls because its near-black depth feels luxurious and pairs beautifully with brass and warm neutrals. Plum suits a bolder, more vibrant statement where you want visible purple color and jewel-tone energy. Choose aubergine for cozy sophistication and plum for expressive richness.
