However, there’s a lot of knowledge behind every formula they mix, even if they make each decision, suggestion and technique look utterly effortless. Not only does it pull up every shade available; it also allows you to see what each colour would look like in different lighting, creating a realistic hair simulation. Koleston Perfect is our purest permanent hair color and the first and only professional hair color combining uncompromised color performance with Metal Purifier and ME+ Dye Technology for true-to-tone color and protection from damage.

To achieve it, you’ll want to reach the depth of a 4/, 5/ or a 6/ then add the tone of a red-violet /5 to achieve that rich, radiant finish, depending on the undertones. Now, you know what ‘color chosen’ means – it’s the desired hair hue – while the ‘starting point’ is a combination of the hair history and the underlying pigment. For example, if you’re naturally a deep brunette 3/ but you want to add a few subtle highlights, lifting ribbons of hair to a 6/ will alter and brighten the underlying pigment, creating the perfect base for a deep caramel toner.When you get your hair coloured, you might hear your colourist reeling off all manner of random numbers. Get the ultimate salon colour now by combining Koleston Perfect Colour with the Wella Welloxon Perfect Developer. Wella Koleston Perfect ME+ is the only oxidative permanent hair dye molecule to replace PTD and PPD that reduces the risk of developing a new allergy to hair colour while delivering uncompromised colour performance.

For example, if blonde hair is yellow and warm but you want it to be icy and cool, you’d look to see which color is opposite yellow on the Color Circle. Not only does it pull up every shade available; it also allows you to see what each color would look like in different lighting, creating a realistic hair simulation. It’s all based on color theory; the understanding that colors opposite each other on the color wheel will neutralize one another, while side-by-side colors will create a whole new hue.

Wella has its own universal numbering system, which means it’s the same across all color products, whether hair is being treated to the pure permanent pigment of Koleston Perfect, or our kind-to-hair demi-permanent, Color Touch. The figure before the stroke denotes the depth (how light or dark the hair is), and the figure after indicates what colour you’ll see. There are various tools colourists might use to find the perfect blend for every client, with the most common being a colour chart or a book of hair swatches.

Meanwhile, if you’re naturally a golden level 8/ but you’re craving a platinum ‘do, you’d need to be lifted to a very pale yellow 10/, before a toner is applied to counteract the yellow.
