15 Deep Plum Hair Color Ideas for Rich, Dark Purple Dimension
Deep plum hair color brings dark purple depth together with a red-violet glow that can look understated indoors and more vivid where light catches it. The range is broader than one solid shade: plum can sit evenly from root to end, melt into a darker base, or appear in carefully placed panels and ribbons. These fifteen visual ideas show how shade depth, contrast and placement work with different lengths, cuts and natural textures. Use them to find a direction that feels personal and easy to explain.
1. All-Over Deep Plum Hair Color for a Dark, Even Finish

A uniform deep plum shade runs from the roots through the long, blunt ends, with red-violet depth visible across the smooth straight hair. The rear three-quarter view shows the full hairstyle and its consistent color, while soft neutral light keeps the dark purple tones readable. A useful reference for an all-over plum finish without highlight placement.
2. Dark Plum Hair Color with a Soft Root Melt

Near-black aubergine roots blend gradually into rich red-violet plum lengths and ends. The long, loose waves show the color clearly from crown to tips, with the brighter plum tones catching the light while retaining a deep, dimensional look. A useful reference for a soft root melt that keeps depth at the crown and carries vivid plum through the lengths.
3. Rich Plum Hair Color with Narrow Face-Framing Ribbons

A rich, dark plum base runs from the roots through long, chest-length waves. Narrow red-violet ribbons brighten the front sections from the temples through the face-framing layers and into the ends, creating visible dimension while keeping the overall look dark and cohesive. The complete hairstyle is shown against a neutral background, with soft light revealing its waves and color variation.
4. Deep Plum Hair Color with Wide Red-Violet Panels

Broad red-violet panels show through the deep plum surface and extend from below the crown to the ends. The shoulder-length layers reveal the color against a dark purple base, with a slight bend that adds movement and keeps the placement visible. Soft, neutral light preserves the rich plum tones in this close hair editorial portrait.
5. Rich Deep Plum Hair Color with Fine Dimensional Ribbons

Long, layered hair blends a deep purple-plum base with fine red-violet ribbons and darker strands through the lengths. The roots remain dark, while soft directional light brings out the subtle dimension. A slight rear three-quarter view shows the full hairstyle against a neutral background, paired with a black high-neck top.
6. Dark Plum Hair Color with a Burgundy-Violet Underlayer

A deep plum base frames this collarbone-length bob, with warmer burgundy-violet tones visible through the lower layers and ends. The rear three-quarter view shows how the red-violet underlayer blends beneath the dark roots and top layer. Loose waves and lightly textured ends add dimension, while soft neutral light keeps the color readable against the pale background.
7. Deep Plum Hair Color with Red-Violet Dimension

Long, loose waves showcase a near-black plum base with rich red-violet reflections through the lengths and brighter plum tones toward the curled ends. The front three-quarter view keeps the full hairstyle in frame against a soft neutral backdrop, making the dark purple color and its dimensional sheen easy to see.
8. Rich Plum Hair Color with a Shadowed Root and Soft Highlights

Near-black aubergine roots blend into a rich, medium-deep plum base, with soft red-violet ribbons through the curtain layers and long, softly waved lengths. The dimensional color is clearly visible from crown to ends in this three-quarter portrait. Subtle makeup, a high-neck black top, and a neutral backdrop keep attention on the hair.
9. Deep Plum Hair Color with Violet-Red Ribbons

Wide violet-red plum ribbons stand out through the dark plum lengths, with softened transitions near the roots. The long, layered shag has a full fringe and textured waves, shown from a rear three-quarter angle that makes the color placement and choppy ends easy to see. Soft neutral light keeps the rich red-violet dimension visible against the understated background.
10. Dark Plum Hair Color with Burgundy Balayage Through Curls

Defined shoulder-length curls show a dark plum base with curved burgundy-violet color along the outer coils from mid-lengths to the ends. The crown stays deep and dark, while the reddish plum accents follow the curl pattern for visible dimension. A rear three-quarter pose, neutral background, and soft daylight keep the full hairstyle and its texture easy to see.
11. Deep Plum Hair Color with a Plum-Black Root Smudge

A plum-black root smudge softens the crown and blends gradually into an even deep plum bob with subtle red-violet dimension. The clean, jaw-length perimeter and natural straight texture are clearly visible in this rear-side portrait, while soft neutral light keeps the rich color readable against the pale background.
12. Rich Deep Plum Hair Color with Copper-Violet Accent Panels

Slim copper-violet plum panels show beneath the dark plum lengths behind the ear and toward the nape, adding a warm red-violet glint. The long, straight hair is shown from crown to ends in a rear three-quarter view, with one side tucked to reveal the color placement. Soft neutral light and the simple background keep the hair’s rich plum tones easy to see.
13. Dark Plum Hair Color with Rose-Violet Face-Framing Ends

A shoulder-length wavy lob pairs a rich, dark plum base with rose-violet color through the ends of the front face-framing layers. The gradual transition is visible on both sides of the face, while the roots remain dark. Soft neutral light brings out the red-violet dimension, and the complete hairstyle stands out clearly against a simple light background.
14. Deep Plum Hair Color with Aubergine Lowlights

A thick, loose braid shows rich deep plum hair with darker aubergine tones woven through its broad sections. The color stays consistent from the slightly darker crown through the textured ends, while soft neutral light brings out the red-violet sheen. This rear angled portrait keeps the full braid and its natural texture visible against a quiet background.
15. Rich Plum Hair Color with Red-Violet Slices on a Textured Pixie

This portrait shows a short, textured pixie with a dark plum base through the sides and nape and vivid red-violet plum slices sweeping across the longer crown. The three-quarter angle makes the layered placement and tapered shape easy to see. Soft neutral light brings out the contrast in the strands while keeping the overall color rich and dark.
How to choose between these hair color ideas
Start with the depth you want: near-black plum reads subtle, while a clearer red-violet plum shows more color across the hair. Dimension can come from close-toned ribbons, a softened root transition or concentrated panels around the face and ends. Consider how the design will look on your haircut and natural texture, since curls and waves reveal placement differently from a smooth finish. Save the examples that appeal to you, then choose according to your own preference rather than a complexion-matching rule.
What to discuss with your colorist
Bring a saved image to your colorist and point out the features that matter most: how dark the base is, where the plum becomes visible, and whether you want a soft blend or defined sections. Ask how the design might translate to your existing cut and texture, and what maintenance it could involve for your hair and routine. Deep color may need thoughtful upkeep to keep its tone looking the way you prefer; your colorist can discuss realistic options. The try-on tool previews color on your existing hairstyle; it does not change cut, length or texture.
