1/2c Brown Black
1c Blue Green
The variation in this colour is difficult to see in the scan above, even though it is quite obvious in the flesh. The blue green comes in a distinctly dull greyish tone as shown in the upper left stamp. Then there is a deep blue green, as shown in the lower right stamp. The lower left stamp is a similar blue green to the one on the lower right stamp, but is a bit less intense. Finally there is a dark green that lacks the bright bluish tinge of the bottom two stamps. This shade is the one on the top right stamp.
2c Carmine Rose
The two basic shades on this stamp are carmine rose, as shown on the left stamp, and carmine-red as shown on the right stamp. If you look carefully, you can see the bluish undertone of the stamp on the left, whereas the stamp on the right does not have this undertone, being more of a pure red.
5c Dark Blue
7c Olive Green
This one of the values in the set that seems to have the more striking of the shade differences. We have from left to right:
- Olive brown
- Olive green
- Bright brownish olive
Next to the 7c, this is the value that I find has some of the most striking shades. Despite Unitrade calling the colour violet, I find that most of the stamps I have seen are variations of purple rather than violet in that they do not contain enough blue to be violet. We have here three shades, which from left to right are:
- Deep reddish purple
- Deep purple
Unitrade used to list both an orange and a brown orange for this stamp, but removed the brown orange listing when it was discovered that the orange ink oxidizes. The left stamp appears brown orange, but there are slight signs of oxidation. So it is difficult to be certain that this colour difference is not entirely the result of oxidation. I do believe that there are some legitimate differences between these two colours, but to really be satisfied, I need to see an example like the stamp on the left that does not have any oxidation. The stamp on the right is the pure orange, which is the colour that you will see on the vast majority of the stamps that you encounter.
20c Dark Brown
I do not have any examples of this stamp in a shade other than dark brown, but I have seen some stamps printed in a brown that has a distinct yellowish cast to it. I will add an image of the difference between these two shades when a suitable example becomes available.
The next post will talk about plate blocks, sheets and plate multiples of this issue.
