Choosing your colour:
For a really natural look it is advisable to stick to your natural hair colour or a shade of it. When in doubt, choose a lighter shade because darker colours can overwhelm your face.
Most hair colours fall into either 'warm' or 'cool' families.
If gold jewellery suits you better than silver then you are in the ‘warm’ family. Gold types are more suited to warmer colours. You will probably fall in to this category if you have golden, olive or dark skin and brown or dark eyes (most Latinas, Asians and African Americans fall into this category). You tan easily and the veins in your inner wrists are green.
If you look better in silver jewellery, you are a silver type. For Silver types, the best colour options are cooler tones. You're a 'cool' if you have fair skin and blue or green eyes. You burn before you tan and the veins in your wrists run blue. If you're confused because you sometimes burn, sometimes tan, you likely skew warm.
If you have warm skin, opt for golden shades such as caramel and bronze in a darker shade than your skin. Avoid jet-black hair which will wash you out and if you do opt for a golden shade, don't go too light.
If you are in the ‘cool’ family, ash blondes and cool browns will work best. Avoid colours that may highlight the ruddiness of your skin tone for example gold, auburn and copper.
If you are struggling to determine your colour type, simply take a hand-held mirror and stand outside in to natural sunlight. Look closely at your hair as the sun is shining on it. Look for the underlying base colour that reflects off of your hair. If you see glimmers of red, orange or gold (yellow) you can choose hair colours with those base colours and feel safe. If the colour glinting off your hair is bluish, purplish or greenish you will want to choose hair colours with the blue, violet, or neutral base colours.
