The complete collection of early pre-decimal stamps, including the unlisted 1956 dull yellow 6˝d (aka 'mellow yellow') Translucent paper is thick paper that has the appearance of thin paper; and this can be a problem to collectors looking for thin paper stamps. No thin paper stamps were issued after 1952, though there have been translucent paper during the early part of the Queen's reign. Prominent translucent paper ('thinner' translucent paper) exists. These stamps are very scarce, especially in blocks. The transparent stamps are part of the 3˝d and 6˝d stamps.

Even with the stamps so well displayed next to each other the color/shade differences to my eye are so slight that I cannot imagine trying to pick these out in the normal course of identifying stamps. |

Hi rogdcam
I agree that some do have a very slight difference, the shades are in ACSC order and though the shades can be very slight, collectors who do have some of these stamps will know what the shade is.
Also, I have replaced the original upload with the same image but with information relating to the unwatermarked and watermarked stamps.

Hello Rob.
Under the blocks of 4 it says No Watermark. Does the No mean a variation? I ask this because I can see a watermark

The toughest to my eye are the violet-blue and deep violet-blue. Imperceptible, at least in this photo. |

Hi Rob041256,
Yet again, your Australian stamp collection amazes me.
Is there any reason why the stamps were issued in so many color variations? For example, the 3#189;d and 6#189;d stamps have 4 color varieties each. And why on different types of paper?
I remember seeing covers with these stamps years ago (my late wife collected Australian covers), but with the stamps having gone through the mail system and exposed to the elements, I doubt the true original color of the stamps can be definitively determined. |

Same with my old eyes looking into this Monitor. |

Hi shermae Quote: The toughest to my eye are the violet-blue and deep violet-blue. Imperceptible, at least in this photo.  Here are the two stamps enlarged. There is a slight difference, All my Australian collection goes by ACSC order, and to find the slightest shade I had to rely on the specialist I bought the stamps from, and my fiancee who has an arts degree.

Hi Jack
Machins are very beautiful stamps, I do collect some British stamps and a few high value Machins.

I still can't see the difference. And strangely, if you look at the perf patterns on the 2 stamps, they are identical. All the little subtle things that should look slightly different are exactly the same. Looks like the same stamp got scanned twice... ? |

I do not understand the delta. How do you tell if the delta is a difference in ink color vs. being slightly heavier inked? Don Edit: I agree with shermae that the image appears to be the same stamp scanned twice.  |

I was not going to weigh in on this color thread, I assume most folks are tired of hearing me harp on this topic. But this thread is a good example of the phenomenon is known as color constancy. Color constancy is a type of bias that our brains introduce which influence how we are perceiving a color of an object. For example, if you looked at a banana under a red light (making it look orange), you likely would still perceive the banana to be yellow. In this case, if told that there is a difference in the two stamps, your brain makes you see a difference.
When we see colors it is all in our heads, it is a subjective sensory perception. Don |
