Show Us Your Colour Changelings!

Couple of common color changes:

following a remark from scotzm "Used Edward vii 1/- values often look like the left stamp but are actually supposed to look like the right one. This is also true of the Victoria 1/- value."
Could you please show the difference between dull green, dark green and deep green given in SG as colour varieties for 1s EdwVII?

By the way... Is this a colour changeling or Scott 37a (copper red)?

Mike33....Here is a easy way to remove the sulfuration on the US oranges....
Take some peroxide.....
pour into a cup....
have a kitchen strainer....place over the cup...
place stamps face down on the strainer.....
exactly over the cup....
evaporation will happen....causing the fumes to attack sulfuration....
check stamps every few days....
after return to normal....gently wipe away any excess on stamp...
no harm to stamp....
ENJOY....
Keep before/after pictures.....post when completed.

Thank you for the illustrations. I have always felt a bit confused.
