Two Cent Washington Color Identification, Please.

In daylight and under UV these are different colored, two are fluorescent. Could anyone assist in identifying the colors.

Sorry finches.

When it comes to stamp color variations, I'm color blind. That has got to be the most difficult aspect of stamp collecting there is. However, not all is lost I do know there are a couple of books that show the colors. But, they are expensive and I don't/won't have them.
I don't recall the titles of those books.

These all look like Scott #220 to me.

According to my Scott Color Guide there are seven different known shades of this stamp.

However, there are also seven different shades of #219D, some of which are very similar to some of the 220 shades (i.e. Carmine Lake and Rose, Dark Carmine Lake and Deep Carmine.) so I think its hard to say for certain. Generally speaking, however, all the shades of the Lake 219D appear to be tinted more greyish-purple than yours.

The fluorescence is probably due to exposure to bleach or other chemicals.

Check out the US National Postage Museum for some examples:

They all seem to be 220.

Thank you members for comments and info'.


P.S. The left Washington has a strong hint of purple in the actual stamp, stands out from the others, not obvious in scan.

Well if that is the case it could be 219D.
It is hard to tell color accuratley from a scan on the computer.

All are 220.

Stamp 2nd from left;
Panda Bear, Under UV the white areas on front and back matches the rest. None show signs of throw away 'bleach white'. Only the red color shines/stands-out a brilliant orange.
