Choosing the right Wella Koleston Perfect Me+ shade starts with three core decisions: depth (how light or dark the result should be), tone (warm, cool or neutral), and the service goal (grey coverage, tonal correction or colour refresh).
In professional salon work, matching the natural base level first and then selecting the correct reflect is one of the most reliable ways to achieve consistent colour results and avoid costly corrections.
At Hairco, we work with salons across the UK that rely on Koleston Perfect every day. The most successful colourists follow the numbering system rather than choosing shades based on names alone.
If you are deciding between two shades, always assess:
-
Natural level
-
Underlying pigment
-
Percentage of grey
-
Desired maintenance level
This approach leads to more predictable results and better colour longevity.
What Do Wella Koleston Perfect Shade Numbers Mean?
Wella Koleston Perfect Me+ uses a straightforward numerical system that indicates the depth and tonal direction of each shade.
Example: 7/1
-
7 = Depth level (Medium Blonde)
-
/1 = Primary tone (Ash)
A more complex shade such as 7/43 includes:
-
7 = Medium Blonde
-
/4 = Red
-
3 = Gold
The number before the slash defines the depth. The numbers after the slash define the tone and reflect combination.

How to Choose the Right Wella Koleston Perfect Shade
Step 1: Identify the Natural Base
Assess the regrowth in natural light wherever possible.
Typical examples:
-
Level 5 natural base with 50% grey
-
Level 7 virgin hair wanting a cooler blonde
-
Level 6 pre-coloured hair with unwanted warmth
The starting level determines both lift potential and exposed undertones.
Step 2: Define the Service Goal
Clarify exactly what the appointment is intended to achieve.
Common objectives include:
-
Full grey coverage
-
Root retouch
-
Tonal correction
-
Gloss refresh
-
Fashion colour
-
Blonde refinement
The same client may require different shade choices depending on the service.
Step 3: Select the Tone Direction
Choose a reflect that complements the desired finish and controls unwanted warmth.
Cool Tones
-
/1 Ash
-
/8 Pearl
-
/9 Cendré
Warm Tones
-
/3 Gold
-
/4 Red
-
/5 Mahogany
Balanced Tones
-
/0 Natural
-
/7 Brown
Step 4: Consider Grey Percentage
Grey percentage has a major impact on formula selection.
| Grey Percentage | Recommendation |
|---|---|
| 0–30% | Fashion shades can often be used alone |
| 30–70% | Blend with a Natural (/0) shade |
| 70–100% | Increase the Natural proportion |
This improves opacity, durability and evenness of coverage.

How We Formulate in the Salon
In everyday salon work, we rarely choose a shade name first. Instead, we assess:
-
Natural base level
-
Existing cosmetic colour
-
Grey percentage
-
Underlying pigment
-
Desired end result
For example, a client with 60% grey at level 6 wanting a cool dark blonde might be formulated with a Natural and Ash combination such as 6/0 + 6/1 to improve coverage and tonal control.
This practical approach reflects how professional colourists create consistent results.
Wella Koleston Perfect Me+ vs L’Oréal Majirel
L'Oréal Professionnel Majirel is another established professional permanent colour line.
| Feature | Wella Koleston Perfect Me+ | L’Oréal Majirel |
|---|---|---|
| Shade numbering | Clear and intuitive | Similar but different reflect codes |
| Technology | Me+ dye technology | Ionène G and Incell |
| Grey coverage | Excellent with Naturals | Excellent |
| Tone families | Broad and easy to mix | Extensive, especially cool tones |
| UK salon usage | Widely used | Widely used |
Both ranges are highly respected. Many colourists prefer Koleston Perfect for its straightforward coding and predictable results.
Common Shade Selection Mistakes
Choosing by Shade Name Alone
Marketing names such as “Pearl Blonde” or “Chocolate Brown” are descriptive, but the numerical code provides the real technical information.
Ignoring Underlying Pigment
Lifting from level 7 to level 9 exposes yellow-orange warmth. If the formula does not account for this, brassiness is likely.
Using Fashion Shades on High Grey Percentages
Without sufficient Natural base, coverage can appear translucent and fade unevenly.
Overstocking Slow-Moving Shades
Holding rarely used tubes ties up cash and increases the risk of expiry.
How Better Formulation Improves Salon Profitability
Correct shade selection affects more than the final result.
Lower Colour Waste
Accurate formulation reduces:
-
Unused mixed colour
-
Repeat applications
-
Corrective appointments
Stronger Client Retention
Consistent colour outcomes build trust and encourage rebooking.
Higher Service Pricing
Premium blondes, reds and corrective work command stronger margins when the outcome is predictable.
Improved Team Efficiency
Junior stylists make fewer mistakes when they understand the numbering system.
Smart Stock Management for Wella Colour
Most salons do not need every shade in the range.
A practical core inventory includes:
-
Naturals from 4/0 to 9/0
-
Best-selling Ash and Gold shades
-
Selected reds and coppers
-
High-volume developers
This covers the majority of everyday formulations while keeping inventory lean.
Many salons reduce costs by consolidating purchases with one dependable trade supplier rather than ordering from multiple sources.
Hairco and Beauty helps salons maintain essential colour stock with competitive trade pricing and reliable availability.
