This Hungary stamp(left) is listed as dull violet. The one on the right is blue. Can violet change to blue?
I'm sorry for poor image, I do not yet have a scanner.

I've just found this, which perhaps explains such a change:
The basic color combination that makes purple or violet is blue and red.
Under most circumstances, red fades the fastest of all visible colors. Short-wavelength light such as blue or violet has greater energy than lower-wavelength light, and red has the longest wavelength of visible colors. Red objects reflect red light but absorb harmful, energy-rich, short-wavelength light.
When light, particularly ultraviolet light, which has a very short wavelength, hits an object, the energy contained within interacts with the exposed surface. The new energy excites the outer molecules of the object causing chemical bonds, thus reducing the vibrancy of the color and the strength of the object over time.

Thank you Ningpo. That makes a lot of sense.

Hi Everyone;
@ seanpashby;
Violet or purple ink colors are created by mixing red and blue. Red as an ink color used in printing is the most easily faded away leaving the blue behind. Your blue looks kinda light bluish grey, so I would say that the blue is also faded just a tad. So no I don't that this is a chemical reaction (sulphurization or oxidation) that is responsible.
Michael##### has a great post somewhere on here where he performed a number of experiments and determined that red fades the quickest. I think he also posted scans of the results.
@ Everyone;
Here is a fact that not everyone knows....artificial light can fade just as much as sunlight. Altho it may not behave the same as sunlight does with regard to different colors.
I have a page of heavy green stock from the very first page of a Scott's Specialty Series album, the one in front of the title page. When I moved a box that was sitting on this page I was shocked to see the shadow of the box on that green page. The shadow was very much darker that the rest of the page. This only took about two months of using a florescent desk light about 6-8 hours per day.
So now I make sure to cover any stamps that are out on any surface unless I'm actually doing something with them, and keep my lights off when not in use.
Just keep on stampin'

I have seen a lot of inks fade from sunlight or chemicals but I have never seen one change like this.
