I think that ambient lighting is often taken for granted, but that it's one of the most important factors in color recognition. That's why I'm excited to announce the addition of a new tool to the Stamp Smarter website that helps you understand how ambient lighting changes the way you see stamp colors.
This tool demonstrates how the color of a stamp can change based on the wavelengths of light reflected from the surrounding environment. The wavelengths used in the tool are the same as those you'll find in most common household light bulbs.

Thank you for this, 51Studebaker. I tried the links you provided. Stampstarter is certainly the best philatelic website I have ever seen. And it looks like there's ample room for collectors to add articles and to display their own collections.

There is another fact affecting colors - your eyes. I had cataract surgery on both eyes recently and immediately noticed whiter whites and bluer blues. The cataracts caused a yellow tint so any judgements on color (even like trying to calibrate my monitor) were off. I have always tried to use reference copies rather than make single specimem (no reference) judgements. Then you have to factor in inks fading/shifting, etc.

What could be an interesting article is how ink colors were created, named by printer, old color naming standards, renamed by catalog makers, new color naming standards, etc. For example, did the printers of a stamp listed as "pigeon blood red" call it that color or some catalog lister. Did the SG Colour key come from some standard or something developed in house?
