Objects that light falls on either reflect, absorb or scatter the light. Some wavelengths are absorbed and others are stopped. the one that is stopped is the one that creates the colour of the object. This is why there are no colours in pitch darkness. Or, colours can be changed by different lights. eg sodium, fluorescent, black lights etc. Photography is so easy these days. just a slide of a scale and a press of a button and you can correct anything. Thinking back to the days of filters to counteract colour casts, it was a real bummer!! Hope I haven't confused you beetle!! Also hope my memory is OK on this subject! Ken :2cents: An extension of this - if a cow ate grass in pitch darkness the grass would have no colour. The milk would be colourless inside the cow - until the cow was milked and the milk then had light falling on it?? Does that sound sane?	kenj (9738)

No, it does not sound sane, it sounds like you have no idea of what light actually is: Light is electromagnetic radiation, that's all, and colour is specific frequencies as in the rainbow . Low frequencies are at the red end of the spectrum and high frequencies at the blue end . Colour as you see it is reflected frequencies of radiation i . e green pigmentation reflects green back to your eyes but absorbs all other colour frequencies . Black absorbs all and reflects none (which is why black items get very hot in the sun) while white reflects all (and stays cooler) . If you could see milk inside a cow, it would appear to be whatever colour the ambient light provided, probably a pinkish colour because of the colour of blood and tissue the light would have to pass through, but subject to normal light it would look its usual off-white .

And it depends on the eyes receiving the light also . Some white flowers (to us) look ultraviolet to certian birds and insects . And as for certain shades of olive green and rust red, they look rather different to my son who has red/green colour blindness .	pctek (84)

The fact that white is white is based on what we have been told in the same way that we were taught what is right and what is wrong - but right and wrong comes only from your parent's point of view. What you see as red, white and blue (I'm SO patriotic) others will tell you is not, or should not be. Confused? I have been for years! Milk is white simply because, although those cows look and act stupid, they are fiendishly clever. Can you do it? R2x1: It has EVERYTHING to do with cowardice, you coward. (Come out from hiding under that bed!) Logic, in this case, does not come into the equation when dealing with SWMBO. My father was very wise: "Women's logic, or lack of." Me a coward? Who said that? Myth: The bumper sticker was no quite right. What it should have said is: "If a man is most definitely, absolutely and unequivocally correct, is he still wrong?" A rhetorical question, eh? And for those of you who don't know or need reminding, "Marriage is a relationship in which one person is always right and the other person is the husband."	Roscoe (6288)
625570	2007-12-30 05:07:00	SWMBO does NOT argue. She states, and that is known as the casting vote. Cowardice is not really involved, just survival. Milk inside the cow is black (at night), since it neither reflects nor radiates visible light at all, that is one of the definitions of blackness. Considering what happens to the milk on the way out, it is no wonder it looks a bit pale on arrival.	R2x1 (4628)

When doing some investigations I noticed that various witnesses all had their own flavour to a certain set of events. If I truly believe the earth is flat then no amount of debate or argument will convince me otherwise. On the other hand I have never seen a report that suggested someone fell off the edge of a flat earth. At this time of the year some people max out the credit card. Presumably (making an assumption here) the said people KNOW this is wrong but they do it anyway. Some people try to manipulate other people for various reasons. Personally I try to base my decisions on experience and also the knowledge handed down by people I trust. I will admit that I don't always get it right! If I did then I would be perfect and therefore I would be a god would I not?	Sweep (90)

625573	2007-12-30 19:53:00	Money can obscure or defy logic for some, - it has for me; After winning a large share of Lotto, I spent too much on premium gadgets (like buying seiko/casio watches on ebay) that I did not really need. I only assumed I needed them, and ended up selling most of them cheap to family members, or on trademe. I was silly really, and it took other family member's logic to tell me that...	kahawai chaser (3545)
