Dust looks dark on light-coloured surfaces but light on dark-coloured surfaces. So what colour is it?  [???]

Both. There's light coloured bits that show up on dark surfaces and dark coloured bits that show up on light surfaces. My PC's black keyboard is dusty- the white stuff is showing up. If I take a white cloth and wipe the keyboard I see dark coloured stuff on the cloth. The dark dust must have been there all along, but I couldn't see it.
Please disregard all previous signatures.

Or... it's grey, so will look pale on a dark surface and dark on a light one?
Never express yourself more clearly than you are able to think.

Would it not depend on the type of dust?

Most household dust is cast-off skin cells, so I heard. A pile of dust will look greyish but, if you add water we are into the same scenario as the 'damp cloth' thread which is running at the same time as this one.
If the dust comes from the Sahara, it makes my car look red - particularly after light rain.

Anyway- as Quentin Crisp  once said - "After two years, the dust doesn't get any worse."
Just leave it there! Try not to look at it.

Enjoy Dust !...especially the dust under printers !

Did you ever give consideration to the Under-printer-Dust-Bunnies ?

Under-Printer-Dust-Bunnies are playful little creatures....they drink lemonade and eat marshmallows !!

If you put your ear close enough you can hear them doing ' bottom burps' which are sweet and fragrant !! ...leave some sherbet out for them and they will love you forever !!
Men are the same as women, just inside out !

He (Quentin Crisp) moved to New York in the early 1980's and lived, as ever, alone in a one room apartment which he famously never cleaned.
 "After four years," he quipped, "you don't notice the dust."

Ah, but if he had travelled at relativistic speeds (in a Yellow Cab through South Bronx maybe?) 2 years may have passed for him but it was 4 years Earth time.  [:D]

I guess I'm just impatient!.
And I love the journalistic "quipped"!
