What am I?

You are a Whiteboard.

I am white. I am dry.

Refers to the color of the board.

Not a dusty green or a powdery black.

Unlike the traditional colors of the blackboard

I compete against smart.

Students write on whiteboard and prove their intelligence.

I think it's

Chalk

I am white. I am dry.

This accurately describes generic chalkboard chalk.

Not a dusty green or powdery black.

Those colors better describe a chalkboard. Chalk in those colors may not be visible on some chalkboards.

I compete against smart.

An alternative to chalk is a stylus. A stylus may be used on a SMART Board, an alternative to a chalkboard for use in classrooms.

I am...

...the "Post your Answer" box on the Puzzling.SE website

I am white. I am dry.

It's white. And it's "dry" in the sense it's barren or empty (or at least it was until I wrote this answer).

Not a dusty green or a powdery black.

Here "dusty green" refers to the background color, and "powdery black" refers to the bar at the top (I think it's called the Stack Exchange™ MultiCollider SuperDropdown™).

I compete against smart.

That's what it is used for.

Are you (stale Kingsmill white-bread) You are white because you are white bread and dry because you stale. You are not green because you are not mouldy nor black because burnt; you are only stale. You compete against Genius 'gluten free' bread.

Iphone. An object associated with apple but not mildew.

• @balazs.com I think you should explain your answer more in general. I have seen multiple answers where you simply write it down without proper justification – SamRoy Nov 8 '19 at 19:48
• But i cant explain it further, I thought it was a white and dry apple with no mold on it. But by the way, I think the "computer" tag should have been added, I particularly have nothing to do with computers, nor with mathematics, believe it or not.)It is not trivial... (That`s why, for example, I add "knowledge" tag to my own puzzles if serious non-trivial knowledge is required.) Just for the future. – balazs.com Nov 8 '19 at 19:59
• An explanation means a line-by-line justification of why you think your answer is correct; otherwise it is more of a guess, or only partial match with the clues in the question. That's all I meant :) – SamRoy Nov 8 '19 at 22:07
