Can hair color change without dying it?

That is possible. Sun can make your hair lighter, but damages it, like going to the sun after using lemon juice, or something. You can also use Henna. Hair color also changes within age.

Yes! Like, my hair was white blonde as a kid. Then it went darker during the years I grew up so now it is a sort or in between thing of dark blonde and light brown.

Yes, you can color your hair with Kool-Aid! With any type of hair. You can boil water & kool-aid it a pot. & wait till it starts to bubble. & then once its ready, poor the boiling water & kool-aid in a cup, or a soup bowl. & dip your tips into the bowl & wait 10mins. Once your done take it out & put your tips under ice cold water. Then brush it. It should stay the color you want for a couple of weeks! Hopefully its good advise!(:
