Mr Blue in the Elux Legend Nic Salt E-Liquid: the legend behind the blue
Every vape range seems to have a blue one, and there is a reason for it. The mysterious blue flavour has become something of a modern classic, a blend that nobody can quite name and everybody seems to love. Mr Blue in the Elux Legend nic salt e-liquid is that flavour done properly, a layered mix of blue toned fruits with a cool aniseed twist running through the middle. It is one of those tastes that is more than the sum of its parts, familiar and strange at the same time, and it has earned its devoted following honestly.
Decoding the flavour, layer by layer
The inhale leads with a sweet, juicy fruitiness that most people read as blueberry, though there is a raspberry and blackcurrant character woven in too. It is that classic blue slush, blue raspberry sweet kind of flavour, instantly recognisable even if you cannot quite pin down every fruit in it. The nic salt base keeps this opening smooth and full, so the fruit arrives rounded and generous rather than sharp, which is important with a blend this busy. It is sweet without tipping into sickliness, and juicy in a way that makes your mouth water on the very first draw.
The middle of the vape is where Mr Blue reveals its secret weapon. Underneath the berries, a subtle aniseed note emerges, a cool, slightly liquorice edge that lifts the whole thing and gives it that unmistakable blue flavour identity. This is what separates a proper blue blend from a simple mixed berry. The aniseed is not overpowering and it never tastes medicinal here, it just adds a refreshing, faintly herbal coolness that threads between the fruits and stops the sweetness from becoming flat. The interplay of berry and aniseed is genuinely moreish, and it is the reason people who love this flavour rarely tire of it.
On the exhale you get a smooth, cool, fruity finish with that liquorice tinged freshness lingering behind the berries. The aftertaste is clean and slightly cooling, more refined than a straight sweet fruit, and it leaves a pleasant tingle that invites the next puff. It is a sophisticated finish for something so easy to enjoy, which is a big part of the flavour's enduring appeal. Familiar enough to feel like an old friend, complex enough to keep you interested.
Who it suits and the mood it fits
Mr Blue has broad appeal, which is exactly why the blue flavour has become a staple. It suits vapers who like fruity flavours but want a little more depth and intrigue than a single berry gives. That aniseed layer means it also draws in people who might normally reach for a menthol or a cooler flavour, because it has a refreshing quality that plain sweet fruits lack. It is a great middle ground flavour, sweet enough for the candy crowd and complex enough for the palate that finds pure sweets boring.
As for when to vape it, Mr Blue is a superb all rounder, which is part of why so many people make it their main flavour. It works morning to night, it is refreshing enough for a warm day yet rich enough to satisfy in the evening, and its cool finish makes it a good choice after food. It suits those long, steady sessions where you want a flavour you will not get bored of, rather than a quick novelty hit. It is the reliable everyday companion of the vaping world, the one you keep coming back to.
How it compares and what to rotate with
Set against a plain blueberry, Mr Blue is far more interesting thanks to that aniseed backbone and the layering of several fruits. Compared to a mixed berry, it has a cooler, more distinctive identity rather than just being jammy and sweet. And against a fruit and ice flavour, it achieves a similar refreshing lift but through aniseed and berry chemistry rather than added menthol, so the coolness feels softer and more woven in. If you have tried other blue flavours across different ranges, you will recognise the family resemblance, and this is a well balanced take on the theme.
Because Mr Blue already carries that refreshing aniseed note, it resists palate fatigue better than a purely sweet flavour, which is one reason it makes such a good all day vape. Still, rotation keeps any flavour vivid. It pairs nicely with a straightforward single fruit for contrast, a strawberry or a mango, so you swing between the complex blue and something simpler and sunnier. It also sits well beside a pure menthol for the days you want only cold, and a dessert flavour when you fancy something richer. Try not to rotate it directly with another aniseed or blue type blend, as the two will start to taste alike and the distinctiveness fades.
Getting the truest taste and looking after the liquid
To appreciate the full layering of Mr Blue, take slower, more considered draws, which give the aniseed time to surface from beneath the berries. Rushed puffs tend to give you the sweet fruit but skip the subtle liquorice note that makes the flavour special. It also tastes at its most vivid on a fresh palate, so it rewards a little space between sessions rather than constant chain vaping.
Storage keeps that complexity intact. Keep the bottle sealed, upright, and out of heat and direct sunlight, ideally in a cool dark cupboard, and give it a gentle shake before use so the flavour is evenly mixed. Heat and light can flatten the brighter berry notes over time and leave the blend tasting duller than it should, so treating the liquid kindly genuinely pays off. Remember that UK nic salt strengths are capped at 20mg per ml, and this is an adult only product intended for smokers and vapers aged eighteen and over.
Who might want something else
Not everyone gets on with the aniseed note, and that is the one thing to be aware of with any blue flavour. If you actively dislike liquorice or aniseed, that subtle herbal edge may put you off, however gentle it is here. Vapers who want a pure, uncomplicated single fruit might also find Mr Blue busier than they were after. And anyone chasing a stark, dry or tobacco style vape will find this too sweet and fruity for their taste. For everyone else, though, it is one of the easiest flavours to fall for.
Mr Blue FAQ
What exactly is the blue flavour?
Mr Blue is a blend rather than a single fruit, built around blue toned berries such as blueberry and raspberry with blackcurrant in support, all lifted by a cool aniseed note. That combination is what gives the classic blue slush character that so many vapers recognise and enjoy without ever quite being able to name it.
Is the aniseed strong?
No, it is subtle and refreshing rather than dominant. The aniseed sits underneath the fruit and adds a cool, faintly herbal lift instead of tasting like liquorice sweets. If you draw slowly you will notice it more, but it never overpowers the berries, so even people who are unsure about aniseed often find they love it here.
Why is Mr Blue such a popular all day flavour?
It strikes a rare balance of sweet and refreshing, which stops it from tiring the palate the way a purely sugary flavour can. The layering of fruit and aniseed keeps it interesting over long sessions, so it satisfies without becoming boring, which is exactly what people want from a flavour they reach for all day.
