How light does hair have to be to dye it blue or purple?

lightening hair up to light brown

  • To dye your hair blue or purple, it has to be at least a light brown.
  • If your hair is that color or lighter, you’re ready to go.
  • If your hair is black or deep brown, on the other hand, you’ll have to bleach your hair to a light brown before you can dye your hair blue or purple.

How many times will you have to bleach your hair?


  • If you have black or deep brown hair, you’ll need to bleach your hair twice to reach a light brown.
  • If you have brown hair, you should only have to bleach your hair once before you’re ready to dye it blue or purple.


Fantasy colors have become very popular recently.

Blue, purple, green, and fuchsia all are very trendy.

Most fantasy colors have to be applied on blond hair, ideally pale blond hair.


But dark colors like blue and purple don’t require such a light base color.

 These tones can be applied on light brown or dark brown hair.

How Light Should My Hair be to Dye it Blue?

Blue is one of the most requested fantasy colors in salons.

Blue hair dye doesn’t need very light hair. Light brown hair is all that’s needed.

Here’s another point to consider: what happens if you mix blue and yellow?


It makes green, of course.

Now imagine if you bleach your hair to light or very light blond.

When you dye your hair blue, it will have greenish tones because of the yellow base tone.

 In this case, your base tone shouldn’t be too yellow, like a light or very light blond. 


How well the blue turns out depends on what shade of blue you choose.

Sapphire blue isn’t the same as deep midnight blue.

 The darker shade of blue, the less important your base tone is. 

Dark blue colors, for example, can easily cover various shades.


That being said, it’s important to remember that blue dye won’t work on base colors such as:

  • Black
  • Dark Brown
  • Brown


The blue dye will simply not show up on those base colors.

 Your ideal base tone depends on what shade of blue you want. 


I would recommend choosing a blue that goes well with your complexion:

  • Medium to dark blues are ideal for pale completions
  • Lighter shades of blue look lovely with dark complexions


Enough about blue, what if you want to dye your hair purple?

That’s what we’ll discuss next.


How Light Must Your Hair be to Dye it Purple?

dark blonde base

Purple is a beautiful, but specific, shade.

Since purple is a specific shade of violet, there aren’t many shades to choose from.

There are simply lighter or darker shades of purple.


 Light or even medium brown hair can be dyed purple without a hitch. 


Purple is made up of blue and red, and a medium brown base color will always have some reddish tones.

Because brown has reddish tones, purple appears much deeper on brown hair than on yellow base colors like dark or light blond.

All of this means that you can apply purple to brown hair without bleaching it beforehand.


As I said, there’s aren’t many variations of purple.

But there are lighter and darker shade to choose from.

  • Light purple is ideal for pale complexions.
  • Deeper purples are perfect for dark complexions.


Are you thinking of dying your hair blue or purple, but don’t know what brand to use?
