Blue And Red Hair Dye Mixed (What Color Will You Get?)
There’s a whole spectrum of colours you can dye your hair, which means there’s an entire spectrum of opportunities for you to be able to stand out amongst the rest!
When you’re picking out your next hair colour at the beauty supply store, you’ll have your options of the standard technicolour shades, blues, reds, and pinks.
But what about colours you can make on your own?
If you haven’t yet tried mixing hair dyes, you’re totally missing out!
It’s something that salon professionals do daily to give their clients the exact shade that they’re looking for, but it’s totally doable for your at-home touch-ups as well!
This applies to unnatural shades, too — like mixing blue and red hair dye!
But what colour will you get when you mix blue and red hair dye?
You’ll get a shade of purple if you mix red and blue hair dyes, but the type of purple is entirely up to what kind of dye you use and the ratio of blue to red dye you blend.
In this article, we’ll break down what to expect when concocting your perfect purple potion and how to go about it to achieve the best possible results! Let’s break it down.
Mixing Hair Dyes
Before we get into the specifics, let’s go over the logistics of mixing your own hair dyes.
It can be pretty intimidating, especially if the only experience you have with creating a custom colour is watching your stylist whip one up for you during an appointment!
We’ll break it down so you know exactly what to expect.
Mixing a custom colour is always possible, but whether or not it’s a good idea is the right question to ask!
Though you can definitely mix any two dyes to create a brand-new shade, some colours work better together than others.
For example, blending contrasting shades (on opposite sides of the spectrum), like platinum blonde and black, probably won’t leave you with an exciting colour.
But colours like blue and red will yield an entirely new result!
Making your own personalised colour is excellent if the shade you’re looking for isn’t available on the market.
If you’re trying to shade-match for a root touch-up, or if you’re just a fan of mixing your own colours.
Is Mixing Colours Safe For Your Hair?
Mixing hair colours is safe for your hair as long as you go about it correctly, so there are definitely some points you need to keep in mind when you’re blending your perfect shade.
Here are some tips you’ll want to consider:
- Never use a metal bowl to mix your shade! Metal containers aren’t ideal for hair dyes in general, even if you’re using a singular shade.
This is because the metal can oxidise the dye’s chemicals, compromising the colour. - Don’t mix brands! If you’re a big fan of a shade of red from one brand and a shade of blue from another, you’re gonna have to choose which one you like more!
Mixing colours from different brands can lead to unsavoury results because of the various pigments used by each brand. - Don’t mix textures! Though you may be using multiple shades from the same brand, ensure the dyes you’re using have the same texture (gel, cream, etc.).
This will provide a harmonious blending process!
What Color Do Red And Blue Hair Dye Make?
Now, let’s break down the technicalities behind blending a red and blue hair dye!
It may seem like a simple process, and it really is, but there are so many shades you could end up with that it’s essential to have this information in your back pocket!
Making A Light Shade Of Purple
Since red is the primary base of the purple colour, the final shade of purple you’re left with relies entirely on that colour.
A bright and bold shade of red will leave you with a colourful and bold colour, whereas a softer shade of pink will leave you with something lighter!
A rose-colored shade can be turned into a violet shade with just a touch of blue pigment, and adjusted to your liking much more easily than an intensely pigmented shade.
Another thing that you can do, if you have access to it, is to mix a true white hair dye into your red and blue mixture.
This may not be super accessible, especially since you’d have to whip up an entirely new batch of dye to adjust your colour, but it’s a foolproof way to customise your purple shade even further.
The main thing to be mindful of is the undertone of the red dye you use.
If there are blue tones, those shades will mix with your blue dye, leaving you with a darker, warmer colour instead of something near violet.
Making A Dark Shade Of Purple
Adversely, you can make a darker shade of purple by using a deeper, richer shade of blue in comparison to the red dye you use!
For example, a royal blue or a shade leaning towards indigo will give you a dark purple rather than something pinky.
If you end up with too light a purple shade, even if you’re using a deeper blue tone, go ahead and mix more blue into your bowl (sparingly) until you’re left with your ideal colour.
This is also a great way to correct your colour if you accidentally grabbed a lighter red shade.
Though it may be risky, using black dye is also a quick, easy way to darken the purple you have. However, it may be in your best interest to skip over this option if you can.
Black hair dye is intensely pigmented, and if you accidentally use too much of it (even a quick drop can be too much!), it’ll be impossible to lighten it back up.
Making Magenta
Looking for a Barbie-toned purple, or more of a magenta shade?
Mix a blue and red light shade — those that are Technicolour and look super bright on their own.
Finding a red that leans towards pink is key to ending up with a true magenta tone.
A hot red with a cooler undertone would be ideal, and blending it with a blue shade that has existing pink or flesh-coloured undertones will help you achieve your perfect shade.
How To Keep Your Purple Shade Looking Bright
When you’re picking out which shades to mix, make sure to find a true blue and a true red to blend.
This means that there are the fewest amounts of yellow pigment in either dye — yellow dyes can seriously compromise the final product of your shades.
Yellow is a complementary shade to purple, which means that when you blend your blue and reds (even if there’s just a little bit of a yellow hue in the mix),
It’ll leave your final shade looking muddy or brown — this clearly isn’t ideal if you want a bright purple shade!
Using Red And Blue Dyes To Adjust A Purple Dye
If you already have purple hair dye on hand and you’re just looking to tweak it a little, you can mix in red or blue tones to adjust it to your liking.
Mixing a deep or bright red colour into your purple dye will leave you with a colour that leans more towards maroon than burgundy.
On the other hand, if you mix a blue into your purple dyes, you’ll be left with a cool-toned purple (perfect if you’re looking for a galaxy-toned hue!).
Mixing Your Dyes With Developer
The developer acts like a lightning agent for your natural shade of hair, which means it’s also responsible for how the final shade of your mixed dyes turns out!
A higher-volume developer will directly lighten the shade of purple you have (like 30v or 40v), whereas a lower-volume developer will leave you with a colour more true to the one you mixed in the bowl.
Make sure that your hair is pre-lightened before dying it to your new purple shade.
A medium-brown to blonde natural shade will take colour well, whereas a dark-brown to black natural shade will need to be bleached before you apply colour.
Make sure to use the same brand and texture of hair developer as your dyes. Using L’Oreal…cream pigments? Use a L’Oreal cream developer, etc.
Conclusion
Mixing a blue and red hair dye can leave you with a completely custom purple shade of hair dye that’s unique to you!
However, no two dyes are the same. For a lighter shade of purple, go with a pink- or cool-toned red dye, and for something a little richer, opt for a deep blue.
Personalising your hair dyes through custom colour mixing is a fun way to vamp up your colouring experience, and when done right,
It will be something you look forward to every time you touch up!
