grotesk

yeah something like that....pot...black...kettle

yeah but slightly more amusing

huh?...so Callipygous, put a different hat and coat on it...and you begin to come around.

as you wish

of course it requires light to be blue, you even said it yourself...

so what external force(s) does the sphere require to exist?...who said the sphere was hard...

colour requires external source to be valid no?...therefore it is a process - you even said yourself it reflects the blue in the white light - isn't that a process?

yes colour is a property and a process, a property of what?....and the spherical substance is a property of blue? not in my opinion. your posts are becoming more and more vague.

a flaw in your explanantion maybe?

and distilled water is light grey??

so are you agreeing it *has* to be a substance?

So what is reflecting the blue light?... like i said define 'it'. is it a substance?...whats the substance? how can you say blue does not rely on light source when you also say it has to reflect light?... oh, and you'll be doing me a favour by ignoring my posts

No i wouldn't thanks for your advice, but its not necessary please define 'it'. again, i'm not after your advice - keep that to yourself. for the pupose of the question we do *know* its a sphere in everyday language, and we do *know* it's blue in colour. it matters not if you are blind, colour blind or just an argumentative colour'phile' the sphere...is a sphere. the blue relies on lightsource AND perception. the spherical property of the object is more of a constant in my opinion, none of your explanations change my mind (not even the patronising ones). what does the blue light reflect off?
