DEMI WB: the warm-brown shade collection
WB is the warm-brown base used across several DEMI dye lines. This collection gathers the WB-coded shades we stock, from the Deep Natural Arias range to acid manicure and self-dye options. Here is what the WB base does and how to choose a depth within it.
What the WB code means
WB stands for warm brown, the undertone half of a DEMI shade code. It sits opposite the cool CB base and the more neutral BB base. Choosing WB tells the colour to develop with golden and warm-brown reflects rather than ashy ones, which suits people whose hair tends to lift warm or who simply prefer a warmer finish.
Depth numbers inside the WB base
The number paired with WB sets the lightness. In this collection that runs from the deeper D-4 / WB up to the lighter D-9 / WB, with D-7 and D-8 sitting in the middle. The base stays warm across all of them, so the number is the only thing changing how light or dark the result reads.
More than one product type
WB is not limited to one format here. You will find permanent Deep Natural Arias dyes, the Aria C Hair Dye 8 WB, an Acid Manicure D-WB Warm Brown for a gentler acidic colour deposit, and a Satch Cover self-dye in D-4 / WB aimed at at-home grey coverage. They share the warm-brown direction but differ in how they are applied.
What the Acid Manicure option is
The Assalt Aria Acid Manicure D-WB Warm Brown is an acidic, non-oxidative colour that deposits tone and shine without lifting. It is a softer option than the permanent dyes, useful for refreshing warmth or adding gloss between full colours, and it does not require a peroxide developer in the same way.
When to pick a warm base
Reach for WB when you want to add or keep warmth, counteract a dull result, or match hair that already pulls golden. If your goal is to cancel red or orange tones, a cool base would be the better tool. The WB shades here are about leaning into warmth rather than neutralising it.
Choosing the right WB product
Decide the format first: a permanent Deep Natural or Aria C dye for lasting colour and grey coverage, the Acid Manicure for a gentle gloss, or the Satch Cover self-dye for a home application. Then pick the depth number for how light you want the warm-brown result. That two-step choice keeps the warm tone consistent while you control the lightness.
FAQ
Frequently asked questions
FAQ
Frequently asked questions
What does WB mean on a DEMI shade?
WB is the warm-brown base code. It tells the colour to develop with golden, warm reflects rather than ashy ones, in contrast to the cool CB base and the neutral BB base.
Which WB depths are in this collection?
The Deep Natural Arias WB shades run from D-4 up to D-9, with D-7 and D-8 in the middle. The base stays warm across all of them while the number sets how light the result lands.
What is the Acid Manicure D-WB?
It is an acidic, non-oxidative warm-brown colour that adds tone and shine without lifting. It is gentler than a permanent dye and is handy for refreshing warmth or adding gloss between full colours.
Can the WB shades cover grey?
The permanent Deep Natural and Aria C WB dyes are oxidative colours built for grey coverage, and the Satch Cover D-4 / WB is a self-dye aimed at at-home grey. The Acid Manicure deposits tone but is not designed for full grey coverage.
When should I choose a warm base over a cool one?
Pick WB when you want to add or keep warmth, or to match hair that already pulls golden. If you need to cancel red or orange tones, a cool base would suit better.
Do the permanent WB dyes need a developer?
Yes. The Deep Natural and Aria C WB dyes are oxidative, so they are mixed with a developer before use. The Acid Manicure works differently and does not rely on a peroxide developer in the same way.
