Shade matching: roots and lengths
Compare roots, mid-lengths and ends separately in consistent natural light. Use the Wella Koleston Perfect shade chart to discuss your starting colour and intended result with a qualified colourist, rather than choosing from a shade name or screen image alone.
| Check | Roots versus lengths | Shade-selection decision |
|---|---|---|
| Level (depth) | Compare how light or dark the regrowth is with the mid-lengths and ends. | If depths differ, record each starting level and the target depth. Do not assume one shade choice will create an even result across both. |
| Visible warmth | Note whether each area looks warm, cool or neutral, including any faded warmth through the lengths. | Decide whether the finished look should retain warmth or appear more neutral or cool. Compare depth and tone separately on the shade chart. |
| Underlying tone | Distinguish the colour you can see from the underlying pigment and previous colour history. | Have a colourist assess these before selecting a tonal direction. A matching depth alone does not establish a matching tone. |
| When to blend lengths | Check whether lengths already match the desired depth and tone, or look faded, uneven or disconnected from the roots. | If lengths already match, do not assume they need refreshing. If they differ, ask a colourist whether a separate lengths refresh or blending plan is appropriate, rather than automatically extending the root colour. |
Before choosing your shade
Bring your target shade reference and colour history to your colourist, including previous colouring or lightening. This guide supports shade comparison, not an individual colour formula or application plan. Follow Wella's product instructions and required allergy-alert and strand-testing guidance.
