A daguerreotype uses a silver or silver-coated-copper plate to develop an image in a camera obscura. The image is formed when the light-sensitive plate is exposed to light through a camera lens.

What is Color Psychology?

But before we colour our hair, we need to understand basic colour theory for hair. Basic Colour Theory for Hairdressing All colours found in nature are a mix of the three primary Art light and color These three pigments produce every known colour in the world, except black and white.

Pigments that colour our hair are found in the cortex Primary colours in our hair vary in molecular size and pigment weight — and this is important to understand in hair colouring.

Blue has the largest molecular size and pigment weight, followed by red and then yellow.

In the hair shaft, blue molecules being the biggest sit closest to the cuticle and blue is the easiest pigment to remove during colouring.

Red molecules are found deeper in the cortex and are harder to remove than blue. This is why red and yellow are harder colours to remove during the lightening process, as these pigments are deeper inside the hair shaft.

To remove red and yellow pigments, the hair shaft needs to be expanded large enough and for long enough during colouring to allow oxidation to dissipate the molecules into the air. Natural Hair Colour Our natural hair colour depends on melanin pigments within the cortex of the hair. Eumelanin pigments consist of all the three primary colours: White and albino hair contains little or no pigment at all.

Why Hair Colour Changes We can change our hair colour by choice through using hair dyeing products. However, hair colour can change for a variety of natural reasons, including: Ageing can affect pigment production.

As we age, melanin stops being made in our hair and new hairs grow without pigment, which is why they are white. Environmental factors can impact hair colour. Oxygen in the air attacks the pigments in hair.

Blue pigments are the weakest pigments and are, therefore, the first to disappear, leaving hair with the warm undertones showing through.

Hence why our hair often lightens noticeably when on beach holidays. Medication can alter natural colour e. Pregnancy can darken light hair due to higher levels of hormones oestrogen and progesterone. Describing Hair Colour The hair colour we see consists of depth and tone.

Hair also has an undercoat of colour, called undertones, which only come into play when we lighten or colour the hair. Depth or Level Depth simply refers to how light or dark the base colour of the hair is. It is also called level, with dark hair having a low level and light hair having a high level.

In hairdressing terms, there are 10 main levels. Numbers are brown black, darkest brown, dark brown, medium brown and light brown and are blonde dark blonde, medium blonde, light blonde, very light blonde and lightest blonde — see the chart below for numbering.

All are neutral shades. Tone Tone refers to the colours we see in the hair, be they natural colours or artificially added. Tonal colours are classed as warm, neutral or cool: Warm tones have reds, yellow and orange in them, and are in colours such as strawberry blonde, copper and chestnut brown.

There is also the ICC colouring systemwith each tone being given a number. Undertones The underlying warm pigment that all natural hair colours have, from red for darker hair and yellow for lighter hair.

ICC is the International Colour Chart system Natural hair has an underlying warm tone, dictated by the amount of the pigment pheomelanin found in the hair.

Life and Bodypainting

Dark hair has more pheomelanin present, creating a red undertone: The undertone becomes more evident when hydrogen peroxide is used to lighten the hair. The undertone also shows through when hair is naturally lightened from exposure to the elements.

Pheomelanin is slowly oxidised during colouring and can produce those difficult-to-remove golden and orange tones in the hair.

When dark hair is bleached sufficiently, it will go from having a red tinge to orange, yellow and, finally, white as the pheomelanin breaks down. Undertone can affect the final colour result when dyeing hair. Correcting or Neutralising Unwanted Tones The colour wheel — essential to know and understand when working in hairdressing or makeup Correcting tones in hair needs an understanding of colour theoryas well as knowing what products to use and application techniques.

To neutralise an unwanted tone, the opposite colour on the colour wheel is used. So, to remove a gold brassy look from blonde hair, we use a purple shampoo or a mauve ash toner to knock out the unwanted yellow.

If the brassiness is more orange, then a blue-based product would be an age of digital illustration, Andrew Davidson is a UK illustrator who uses some of the most traditional illustration techniques from previous centuries, wood engraving, color woodcuts and gouache painting.
