To me it means you don't need any explanation to browse the website and you feel at ease when doing it.

Personally when I say a "clean design" I mean something that has no clutter, clean lines, color harmony, consistent spacing/margins/paddings,etc. Something that not only is "pretty" but shows the content in a way where everything has it's place. Organization. No noise. If any of that makes sense.

That sums up my definition lol. I was surprised that the color white was the first thing that came to my mind but I don't think that should be the case...but those are the ones that appeal to me I guess. *shrugs

For a long time I confused a clean design with minimalistic design. My preference is clean.

I think if it's legible, uncluttered and the point is clearly put and you get your point across it's clean.

Color palette should not clash but there isn't a COLOR that defines "clean" I've seen beautifully clean designs in purple, green, piss yellow and burnt orange.

@RightOn - You're right about color but for some reason I can't think of a site with a clean design that isn't basically white (or light). I know there are zillions out there and I will feel dumb about not being able to remember one if I ever think of one. I just went to Template Monster real quick because I know they have a collection and the vast majority are light in color (but not all of them are what I would consider clean though).

Haha, this is funny I can't think of a clean dark site.

See, to me this is clean...

Red

Pink

Green

Blue-ish

needs moar whitespace.

No b.s.

More whitespace (cowbell)

It means I don't get a seizure when I look at it. It also means that everything on the page has a purpose besides 'Oh man, the CEO really wants to have Flash'.

'Oh man, the CEO really wants to have Flash'.

cracked me up because its true.

'Oh man, the CEO is a total idiot!'

It means this.

Clutter-free, simple, good use of empty space, balanced layout, even lines...

I love clean design. Hoever, I don't think it's sensible to say you specialise in 'clean' design as it's a bit one-track and it's not the only way.
