This 25 reis Potlrtugal , Azores islands stamp has a difference in color on it's upper part . Is this just a result of fading of the stamp ?

Looks like it is darkening.

It could be sulphide blackening of a chalk surfaced stamp, which contained white lead.
Seen before on Portugal Stamp.

Opinion.
On further study, it looks like a Portugal Sc# 66 1887 Overprinted
Colour should be Lilac Rose.
Ergo, yours is badly light damaged (colour changeling)

I think these were printed on enamelled surface paper ?

The change of the color contrast the lower part of the stamp and this looked unusual to me , because as you've mentioned the color of the stamp had to be Lilac Rose. I looked some other stamps from the same issue and there were all with the normal color. If I understood your post correctly the color on the upper part of the stamp was changed because it was put under strong light .

No, sorry,
I mean the entire stamp is faded, Lilac Rose is very much stronger.

These stamps do fade badly in my experience
I'll dig out some examples, stand by

The confusing thing is, there is an overprinted example of type A26
as "Rose Lilac"
I am not a specialist, so if any members can enlighten us
we all could be the wiser.
"Colour changelings, or ?

The colours given in my old SG catalogue are magenta and rosy mauve.

Aha! Thanks Geoff
Solved that one, Scott fails to list the 1889 in my catalogue.
So the OP stamp looks pretty normal for me.
