Which blue to add to a too-olive green?

[GNL]

I've recently purchased a bottle of Diamine Dark Forest, which I was hoping would be more of a fir-tree green, but is, in fact, close to olive.  What blue ink (presumably Diamine) should I blend with it to create a more beautiful, less olive, color?

 

Thanks!

Remember to mix in small vials.  I think I'd add a gray leaning blue.  Somewhere around here is a link to a site that helps you with additive color. Perhaps @LizEF or @InesF can help.

I gave up on ink mixing early on, but some lessons I learned:

1. Do chromatography (you can use white coffee filter paper for good results).  This will tell you whether your blue has other dyes in it that will cause unexpected results.  For that matter, do the same on the green ink.  If you can't do this for some reason, look for reviews that have done it for you - here or on YouTube would probably be your best sources.  On YT, An Ink Guy and Matt Matteson both do chromatography, as did VittaR.  I'm sure there are others, but those come to mind.
2. Work in a sample vial with small quantities.  Keep track of ratios.
3. Definitely find some online color mixing sites to help you figure out the shade of blue to add to your green.  There are apps that you can use to get the hex code of your green ink via your phone's camera.  And there's https://InkSwatch.com/ to help you find inks close to the hex code of the color you need to add to your green once those sites have helped you find it.  Research here will be a time-saver compared to experimenting with various blues, IMO.

Best wishes!

Interesting. It looks pretty cool-shaded in pics I've seen. Could it be that the red sheen is the cause? If so, maybe try diluting.

 

It may be hard to get the color change by just adding blue.

 

What diamine blues do you own?

+1 to @LizEFs answer!

Do it in small volumes first and if you want avoid a grey undertone, use a green leaning blue.

I went and looked after you posted this, and yes, it doesn't look possible for that ink to seem the least olive-y.  Makes me wonder if maybe @GNL got a bad or mislabeled bottle.
