Changing your hair colour is one of the quickest ways to feel like a new version of yourself — but staring at a wall of swatches (or a salon colour chart) can be paralysing. Should you go warmer? Cooler? Lighter? Bolder?
Here's how to narrow it down with confidence, and how to make it happen.
Start with your skin's undertone
The single biggest factor in a flattering hair colour is how it works with your skin's undertone:
- Warm undertones (gold jewellery suits you, veins look greenish) are flattered by warm, golden and rich tones — honey blonde, golden brown, warm copper, chocolate.
- Cool undertones (silver jewellery suits you, veins look blue) glow alongside cool tones — ash blonde, cool brown, blue-black, soft mushroom shades.
- Neutral undertones can carry both, which gives you the most freedom.
A simple rule: a colour that contrasts your undertone makes a statement, while one that harmonises with it looks soft and natural. Neither is wrong — it depends on the effect you want.
Factor in your eye colour and natural level
Your natural hair "level" (how light or dark you are) affects how much work a change takes — going dramatically lighter needs lifting and more upkeep, while staying within a couple of levels of your natural shade is gentler and lower-maintenance. Your eye colour is a handy guide too: warm-toned eyes (amber, warm brown, green-gold) tend to pop with warm colours, while cool eyes (blue, grey, cool brown) suit cooler shades.
Be honest about maintenance
The most flattering colour in the world isn't right for you if you can't keep it up. Ask yourself:
- How often can you visit the salon? Big changes and cool tones need more frequent upkeep; lived-in, root-smudged styles like balayage stretch further. (See "Balayage vs Highlights" for low- vs high-maintenance options.)
- How much home care will you commit to? Colour fades without colour-safe products — Insight's vegan Colour Care range helps it last.
Want to experiment first?
If you're not ready to commit, semi-permanent colour is a brilliant low-stakes way to test the waters. Insight's vegan Incolor Direct Pigments are ready-to-use, vibrant semi-permanent shades — from Rich Silver to Blue Velvet and Fierce Copper — that gradually wash out, so you can play with bold colour without a lifelong commitment.
(If you do try colour at home, always do a patch test first.)
Getting your colour done properly
For a permanent change, a big lift, or natural-looking dimension, nothing beats a professional colourist. Insight's professional colour is created in the salon using vegan formulas — so the most reliable route to the shade you've fallen for is to ask your colourist for Insight colour, and let them tailor it to your skin tone, your hair's condition and the upkeep you can realistically manage.

Frequently asked questions
How do I know what hair colour suits me? Start with your skin's undertone — warm skin suits warm colours, cool skin suits cool tones, and neutral skin suits both. Your eye colour and natural level help fine-tune the choice.
What's the most low-maintenance hair colour? Colours close to your natural shade, and lived-in techniques like balayage, fade softly and need fewer top-ups than dramatic lifts or cool, ashy tones.
Should I dye my hair at home or go to a salon? Semi-permanent colour (like Incolor Direct Pigments) is fun and forgiving to try at home. For permanent colour, big changes or lightening, a salon gives safer, more reliable, more flattering results.
How can I make my colour last longer? Use colour-safe shampoo and conditioner, wash less often and in cooler water, protect from heat, and keep brassiness in check with toning care between visits.
