What is my hair color?

Hey, guys! I need your help figuring this out.

I usually identify as a brunette, because my hair looks rather dark when I'm indoors indoors/in places with not enough light. I snapped a picture where my hair looks the darkest: http://img143.imageshack.us/img143/2636/2010070144606.jpg

But this is what my hair looks like in the sun/when there is sufficient light:

So, what color is it exactly? Is it light brown, dark blonde, reddish brown or something else?

From those photographs I'd say what mine used to be. :D Golden brown with hints of auburn.
