34: Colour and Style Q&A: Can my arms be a different undertone to my face, buying clothes is more than just picking colours that match your palette, What colour can I dye my hair?

Can my arms/wrists be a different undertone to my face?
Until now I’ve just been looking for any colour that matches my colours swatch when buying clothes – I now see I need to think about taking my colour and value contrast into consideration as well.
I don’t want to go grey so what colours can I dye my hair?
