How do I get food coluring out of my hair?

Is it posible to get red food colouring entirely out of my hair in three hours? I have light blond hair and I got alot of red food colouring in it and its not coming out. I have to get the majority of it out by today but it has to be entirely gone by monday. If anyone has any tips or ideas on how to get it out it would be greatly appreciated. Thank you

Also if you dont have an awnser to my question not put "i dont know" because that does not help me at all.

Any color you get on light blonde hair is fairly permanant so you will have to decolor or bleach to get rid of the color.
