how to go from blue to blue in a couple dozen easy steps

my hair is blue again
it was purple last
before that various shades of red, orange, pinks
[all the colors of the best tasting kool-aides]
not a teal
but a bright vibrant blue*
i'm in love with it
and i'm not just saying that so it'll stay the night

*if i had a hosting program, i'd post pictures.**
**but i don't.
