Dying my hair red?

I naturally have dark brown hair (it's almost black), and I think I'd like to be a redhead! I don't want a carrot-top red, I'm thinking more like Isla Fisher or Amy... show more I naturally have dark brown hair (it's almost black), and I think I'd like to be a redhead!

I don't want a carrot-top red, I'm thinking more like Isla Fisher or Amy Adams:

Or maybe a darker red, like Julianne Moore:

So, how do I go about this? Is it even possible? What shade do I need to choose and what (in your opinion) is the best brand of home haircolor? Basically any advice about dying my brown hair to red at home ;)

*Please don't tell me to go to a salon, as I have been dying my own hair for over five years - it is very healthy and I think I've got the routine down ;)

Thanks!
