Are there any permanent/ demi-permanent hair colors available in funky shades (like blue or purple)?

Any of those "funky" colors are actually stains that are put on over bleached hair so they don't set the same way. How you set the color can effect rub-off or fade, as can the natural porousness of your hair. Heat-setting the color and then rinsing with vinegar can help.

Organic Color Systems has 67 intermixable colors including "fashion colors" like blue or purple. hubpages.com/hub/Professional-Hair-Color.

Yes most hair color companies have a funky hair color line. One of my favorites to use is paul mitchell's Ink Works line.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
