so I can try to use it to compare my stamps?
You are left to your own devices.
I'd suggest you collect all items together, and compare yourself.
As far as I know, only Scott differentiates the colours, I do not have Brusden white for this year.
NOTE: Scott refers to the colour of "AUSTRALIA" and the value figure, (Not the bottom panel) although this may give you an better appraisal.
Below is the Korea sheet, and a "block"
In the third scan I have placed the block alongside the souv sheet, for comparison.
Bright Orange only exists on 1274B, 1275B,1276C, 1277B, 1278B and 1279E
I'd suggest my block is "bright orange"
I am unsure if these are "Koala and Kangaroo Reprints" I don't think so.
