Help with Australian Stamps

[tomd]

I have a question to ask about a series of Australian stamps.
The series is the "Food Production" of 1953.
There are 3 stamp types, one for Butter, Wheat, and Beef.
They are also priced at, one set at 3 d's and the other 3 ½ d's.
The 3 d's are colored emerald and the 3 ½ are scarlet.
Scotts catalog does not show the names for the colors or shows that there are more then one color. 
The Stanley Gibbons "Australia" catalog shows there names of the two colors and which one is which.

Now for the question for the Australian stamp experts.

A web site that I use, australianstrampcatalogue.com/1953.php
shows the two set with there colors, BUT, the 3 d emerald show two different emerald colors.
One light and one very dark.

Are there different catalog numbers or are they the same but different shades of emerald?
They look very different and should be different catalog numbers.
Does any one have any insight on them for me?

Not an Australia expert, but as far as I know there is only recognized color for each denomination.

On the website, for each denomination, the left 3 stamps are used and the right 3 stamps are an unused setenant strip of 3. While there may be slight variations in shade over the production run, my guess it is more of an issue with the scanner setting (3½d red strip color is off) and color changeling on the used stamps (compare color of top and bottom panels of the 3½d used stamps).

I'll leave it to the Australian experts/bears to confirm or correct me.

Thanks khj, I did not notice the used vs the unused.
But even with that, I was not sure with that big of a color shade difference to be as you say a scanner or usage factor.
But the Scotts and the Stanley Gibbons catalogs not showing the difference I was just unsure.
I checked another site "poppe-stamps" as well as "catawiki", and I did see a color difference.
That I would think take the scanner part out since there was more then one.
And I have none of these to compare first hand.

There is still a scanner artifact, as the unused 3½d strip color appears way off -- it looks almost orange on Dodd's site. Again, I'll leave it to the others to confirm/correct.

Of course, orange color is always good.

Greetings Mr. tomd

For what it is worth, I just took a gander at those critters in my album and noticed the color in the bottom banner is different from the rest of the stamp. It is more noticeable in the 3-1/2-pence stamps. The top banners are "scarlet" and the bottoms are a "red orange." On the three-pence I would describe it as dark green and light green.

This is my only two-pence worth on this subject.
