Here are some KWZI green inks I was graciously sent to allay my confusion between #26 IG Green #1 and #25 IG #2.
I must say that after trying them both out, they appear to be just about the same ink.
Though an error in the labelling of sample of #2 and the bottle of #1 I used is a possibility.
In my written example the two seem a bit different. #25 IG green #2 is more green and is a slightly lighter and less saturated colour.
#26 IG Green #1 is a bit richer and has a tiny bit more blue in the darker parts.
But the line separating the two written examples was done at the end of writing with IG Green #1, yet looks exactly like IG Green #2.
And both have some blue as seen from the wet drops. Apparently #2 Green should not have any blue. #26 IG Green #1 had more blue throughout initially and was less obviously green, but then upon drying the inverse became true. But they are very, very close. I have to say, it almost seems that if #26 were diluted slightly it would be exactly like #25.
On a further wet drop test I can hardly tell the difference between the two.
And in a q-tip swab test there was absolutely no difference between the two inks.
I am convinced that any differences on paper were due solely to differences in the pen's nib/feed wetness at the moment of writing.
#36 Menthol Green is a vibrant but messy colour!!
I got splashes on the table that usually if cleaned within seconds comes right off. But Menthol Green was hard to clean and stains remain.
The demonstrator was also difficult to clean out after only a few minutes of exposure to the ink.
It's a beautiful colour, but be careful with it.
#42 Rotten Green is a unique colour. I'm not sure where it would come into use, but it was certainly interesting to try out.
#27 IG Turqoise goes on sky blue and darkens dramatically to a colour that could almost be used for business correspondence. The more I look at it the more I like it.
#75 IG Green Gold went on so light and lime coloured with the Nemosine Singularity medium nib that I flushed the pen and tried again.
With a wetter TWSBI 580 it went on darker, but still pale, yet darkened quickly and dramatically.
It has a minor amount of sparkles and is much more toward green than gold. Shading is spectacular.
