Amber
This is a bright orange/yellow tone ink. Not one that I would have every selected on my own. I did receive a note written in this colour tone and the vibrant tone of the colour on the short note was impressive.
I have now used this ink to write some cards and it is distinctive.
The colour is fairly close to the colour swatch on the Diamine web site.
Blaze Orange
There is only the slightest difference in colour tone between Blaze Orange and Orange.
I found the colour of the ink was lighter in orange tone than the colour swatch on the Diamine web site.
Coral
A very light pastel orange colour. There is a tinge of pink to this ink.
Special purpose type of ink, cards etc. but not a colour that would be used for business writing.
Orange
I found the bottle of Orange that I have to be just a little more darker in tone than Blaze Orange.
It is a special note type of ink, looks great on a card with just a few lines of writing.
I
see the colour swatch on the Diamine web site also shows the Orange as ever-so darker than Blaze Orange.
Pumpkin
This is a new ink that was issued in the later half of 2009. When I first wrote with the ink I was impressed by the depth of colour. The ink has real punch.
Good flow and it preformed pretty much like the other Diamine Inks.
The colour has enough depth that it has a presence on the paper.
The colour swatch on the Diamine site has a little more red than what I found in use the ink in various pens/nibs.
