The Science of Colour: Understanding What Works for You

Marcus Webb
Hair Colour Specialist
Hair colour is chemistry before it is aesthetics. Understanding the science behind why certain shades complement certain complexions — and why others work against you — is the foundation of a great colour decision.
Colour theory for hair begins with undertones. Every person's skin has an underlying warmth or coolness — a base note that influences how colours read against the complexion. The most common mistake in hair colouring is selecting a shade in isolation, without considering how it will interact with the specific undertones of the individual's skin.
Cool skin undertones — typically characterised by blue or pink hues at the wrist — are complemented by cool hair shades: ashy blondes, cool browns, blue-blacks. Warm undertones — golden, peachy, olive — work with warm shades: golden blondes, rich caramels, warm chocolates. Neutral undertones have the greatest flexibility, working with both cool and warm families.
Grey coverage is a nuanced art. The goal is rarely to eliminate grey entirely — complete, uniform coverage often looks artificial and ages a person as much as uncovered grey does. The most flattering approach blends the grey rather than erasing it, creating a result that reads as a natural, vital hair colour rather than an obvious dye job.
At Luxe & Co., our Bespoke Colour Treatment begins with a thorough colour consultation conducted by Marcus Webb. Marcus analyses skin undertone, existing hair colour, growth patterns, and the client's lifestyle before proposing a colour formula. The strand test that follows confirms the predicted result before full application. This level of process is what separates great colour work from disappointing outcomes.
Product quality is non-negotiable in colour work. We use exclusively ammonia-free, professional-grade colour formulas that provide full coverage and vibrancy without compromising scalp health or hair integrity. The conditioning treatments we apply post-colour help seal the cuticle and lock in the result, extending colour life significantly.
The maintenance conversation is as important as the initial application. Marcus provides every client with a detailed home care plan — the right shampoo, conditioning protocols, and recommended timeline for next appointment — to ensure the colour investment is protected and extended.
