I personally think, it’s Brown, but my colleagues insist it is Blond, which color is it?
Since the OP is seeking opinions, let’s move this to IMHO.

Which one?
There’s only one person?
I’d say light brown, but it can be hard to tell for sure from a single photo. Lighting effects can make blond hair appear darker, or hair of a medium shade can look lighter.
It’s brown. A lot of people lie to themselves about their own hair color and then try to apply it to others for consistency’s sake.
Light brown. I wouldn’t call you blonde unless your eyebrows were equally light.
I read this thread to see who replied.
Looks blonde to me. At least, it’s blonder than I am, and I usually get called blonde.
I’ve done this once just for kicks while shopping.
What you do is go with someone to a store that has a large hair dye section and find the one that matches your natural color best.
Could be that you have longer hair that gets exposed more to the sun, thus lightening it like his is at the ends? That used to happen to me a lot when I was younger. Lighter hair when I grew it longer. It was the 60s. 
Mine looks very similar and my hair stylist says mine is dark blonde.
When I was in grade school, there was a girl with blond hair. One brother had red hair and the other had brown. Their mother’s hair was black, and their father was graying.
‘Audubon’.
‘Audubon some other colour!’
(An old joke my dad used to say.)
My hair is that color. On my driver’s license it says brn.
My sisters used to call it ‘dishwater blond’. I had mean sisters.
What color was * their [/] hair?
…are you old enough to be here?
Yes. And who replied?
To the OP - you’re a young dude. Worry about that stuff much later. Gotta go with brown, though.
The definition of blond isn’t set in stone. Blond Jesus, for example, almost always was your hair color or darker.
It’s all relative. When I got light brown highlights, people thought started calling me blond. When I looked at my hair, it was still light brown, but the contrast made it blonde.
If you were around a lot of dark haired people, I might consider you (dark) blond. Around a lot of light haired people, I’d probably call it (light) brown.
I wouldn’t call it dirty dishwater, as I reserve that for people with natural darker highlights in lighter hair. (And, yes, I call them highlights even when darker.)
