  Pink copper? (Message 1 to 7 of 7)

A few years ago, a store clerk handed me some pennies that were 
obviously fresh off the mint.  I remarked to him how pink they looked, 
and he thought I was crazy.  Well, I know that 8% of human males have 
some deficiency in color perception, but although I have not been 
formally tested, all evidence over the years indicates I am not one of them.

Over the past few days, I've received a few fresh pennies, so I present 
to you a couple of Awsome Rolexes of these almost-virgin beauties for 
your inspection.  So why am I posting this here instead of p.o-t? 
Because I will try to compute a nominal RGB value (taking the 
environment into account) and submit it, among other values, to the 
Object Collection.

new_pennies.pbi.jpg was shot during a brief window of sunshine between 
snowstorms (smirk!), using daylight white balance. 
new_pennies-flash.pbi.jpg was shot with a Nikon flash of some sort, with 
uncertain white balance.  I put the hazelnut there so that the autofocus 
wouldn't go nuts.

So what do you think?  Pink or not pink?

____________________

P.S. Speaking of the Object Collection, I /really/ think someone should 
take a look at the message I posted in p.o-c a couple of weeks ago. 
While I trust the lawyers at the FSF, I can't say the same for any 
lawyers who might challenge POV-Ray in the future.

Certainly look pinkish to me, but then, I am one of those people who, 
when doing the whole online, "Match the color gradients correctly.", 
tests is only confused by like two out of 50, or what ever it was. The 
average for men, and even most women, is, as I understand, much much 
worse than that.

It looks like copper colour. :-P

Seriously, definitely pinkish. :-)

Pinkish, no doubt. The daylight ones look most natural to me, and most 
pinkish; the flash ones are not pink at all.

Maybe it is the metallic sheen that confuses people about the colour.

I won't give any statement on that one without cutting out a patch from 
one of the coins and pasting it into a neutral gray blackground. The 
human visual system is too good at compensating for the lighting 
conditions and other environmental effects to make any objective 
observations on individual colours in a complete image.

That's remind me this illusion.

The daylight one is much closer to my visual impression.

No doubt.  That's why I used white paper as a backdrop.
