Grt Britain KeVII One Shilling Color Difference

Hello, hoping someone can explain the color difference on these 2. Is it just a printing shade difference or an error?
Thanks!

Scott lists 138 as having four different colors:

Carmine and Dull Green
Scarlet and Dark Green
Scarlet and Deep Dark Green
Carmine and Light Green

There is also a version on Chalky paper, listed as 138d. That one is listed in two different colors:

Carmine and Dull Green
Scarlet and Dull Green

Good luck figuring out which ones you have, but I also have the same shade differences.

Very helpful and appreciated. Thank you so much!

Yours is a color change due to sun or chemicals ,the span of shades in the green is four or five shades

Also if you soak the Jubilee stamps don't they have a tendency to run- as in the color runs off and they fade easily?

The QV and KE7 stamps of this design are notorious for fading when immersed in water. This was by design.

Therefore, the identification of shades is considered unreliable for such used stamps. By at least some collectors, shade ID is unreliable for used stamps in general, i.e. is only applicable to well-preserved mint stamps even though catalog pricing is given for shades.

I feel confident in saying the 2 on the right of the top row, and the bottom left are water damaged the watercauses the ink to dilute and run. The bottom row 2nd from the left might also be suffering from having got Wet. If I have to soak one of these jubilee style, multi coloured stamps I soak a wad of Kitchen towel and put the stamp face up on top of the damp paper checking frequenly to see the paper is not soaked and if the hinge remnant or whatever will come off. It's not a foolproof method but it almost always works for me.

Good advice Noocassel :) - aside from QV and KE7 Stamps are there others with this intentional fading when immersed in water? I ask because I receive some British Colony stamps in WW lots I purchase (and you know I collect GB) and at times I hesitate to soak the hinges off a used stamp - because I think about these issues and I do not want to ruin the stamps. Gracias Nora.

Green and Bright Scarlet

Green and Carmine

Beautiful. Very very nice.

Thanks NSK for confirming what I post on 2-11-22,that there are a few shades of green in this stamp .

Well done, rogdcam. Others may snipe, but these scans look exactly as they should to my eyes and monitor.

Mrita, the two definitive sets of Netherlands Indies of 1993-40 (Scott 164-88, 200-25) were also purposely made with fugitive inks. Bright reds of the 19th Century can be fugitive, like some US 2c Washington Small Banknotes and first Bureau issues, the Japan 1 yen with embossed chrysanthemum (Scott 84). You've maybe already found the red lozenges on airmail envelope paper can bleed during soaking. A short soak in rubbing alcohol (60%-70% type) afterwards might reduce or eliminate that staining.
