Why you shouldn't dye blonde hair blonde

I naturally have blonde hair.
It was nearly white when I was a toddler, and when I was about seven, I started getting these dark streaks underneath.
A lot of people complemented me on it, and I guess I sort of liked it. I really can't remember.
About three years ago, it started getting really dark.
I look like a brunette.
Nothing against brunettes: my mom's a brunette and my sister is a brunette.
I just like the excuse being blonde provides don't like it on me.
I got highlights two or three times, but they were really expensive.
After that, I figured dying my whole head for $7 is better than dying half of it for $100.
Nope.
The first time it turned out orangey and brassy.
Lasted for a while, then I asked my friend to help me dye my hair.
That one turned out less brassy, but still wasn't the blonde I was looking for.
Fast forward to now, about two months later.
I took a shower and thought the water looked funny. I thought it was just the water; we've been having storms lately, and sometimes that affects it.
Got out, and didn't think anything of it.
Come back a few hours later . . .
ORANGE. RESIDUE. EVERYWHERE.
I honestly cannot remember what brand or what it was, but I know it foamed.
I'm not saying this is a typical result either, because I wasn't using special shampoo or anything.
All I know is that I washed my hair and my white bathtub turned orange.
This is also why you ought not dye blonde hair blonde: it's nearly impossible to nail the color yourself, and unless you want to look like a pumpkin head for about two months, I'd just stay out of the hair color aisle all together.
