You could chalk your hair. There are loads of videos on youtube on this.You can have a different colour everyday. But the process dried your hair so if you do go ahead with it make sure you moisturise your hair more than usual.
If your hair is as dark as the pic...then have you considered a gold mascara or other type of colour that would add subtle highlights, yet wash out as make up would?<br />
Also, there are the spray in glitters....in the uk shops like Clares Accessories sell them...you could try masking the hair you dont want to highlight and spraying small streaks....
