I got the idea after another post I did regarding gold and what different karat weights of gold densities were.
Where I live most of the gold I see is high karat gold, probably in the 18k to 22k range. I have heard it said around here that this high of karat weight gold is not the norm and that most native gold is lesser karat. In that post I did, I listed some of the different metals that alloy with gold, mostly silver. And although I know that royal purple gold is alloyed with aluminum, I do not know if it actually ever occurs naturally. The same with 'blue gold' which is alloyed with iron. Iron is very commonly associated with gold and I imagine that it might be alloyed ocassionally with gold, however I really don't know if it actually ever is or not in nature. Maybe it's a man-made alloy only.
It would kind of be nice to see people's gold, and the color it is. Gold alloyed with copper which is somewhat common is rose gold. So there is a whole color wheel of gold. I have some gold here that is pale yellow and is likely high in silver. It came from the Rich Hill mining district.
So my thought was for people to take a picture of some gold they have and post it along with the rough area of where it was found, to see what different colors are where in the USA.
The problem is that there are a lot of different cameras and lighting. True sunlight, incandescent lights, fluorescent, etc. So to get a true idea of the colors to compenaste for different cameras and lighting I thought it might first be good to have some standard color items that could be placed in the pictures. One example might be a Marlboro pack for the red and white, or a dollar bill for the green. Any ideas there on the color standard items? Pepsi can for the blue and red??

. But what I would like to know, is how a detector reacts to the different gold. Gold with iron cannot give the same signal as gold with copper, at least I dont think so.
