In a recent thread on the Toucan ink range, someone asked a question about mixing the inks - specifically red (Crimson) with black. Somewhere or other I indicated I'd check it out if I found the time - but can't remember which thread, so thought I would post this here.
A general comment, first of all: the designers of this ink specialise in paints and dyes of all kinds, and manufacture most of their products to allow mixing of colours. This extends to their inks - they've been intentionally designed to allow mixing. With my older daughter, I've created a 'peach' colour by mixing orange with magenta (which should be called pink) - she likes to use it in one of her cheap pens. I've also tried mixing crimson with violet (I think it was) to create a maroon or burgundy - though it's not as vibrant as the Platinum purple (Preppy) colour I was trying to mimic. I hadn't tried mixing with black before - so this is my first try.
The picture first, then the explanation:

(1) I started with one of the pens I'd inked with Crimson on Friday (a 'Classic 626', as per previous post) - sample top-left.
(2) I dumped the ink back into my sample vial of crimson ink, then drew out 2ml of Crimson (roughly) with a syringe - deposited into a fresh, clean vial.
(3) I added roughly 0.2ml of Toucan Black ink with a 3ml syringe, agitated the mixture vigorously, then flushed the new ink colour in and out of the pen by turning the cartridge converter piston back and forth several times - then wrote the sample, top right.
(4) I dumped the contents of the cartridge converter BACK into the vial, and added ANOTHER 0.2ml of ink (roughly), then flushed the ink back in and out repeatedly as per step (3), before writing the sample, bottom right.
(5) Dumped ink back into vial, added another 1ml of Crimson, agitated, flushed repeatedly through nib, then wrote bottom left sample - unfortunately I omitted to wipe excess ink off the nib tip, so the top line was excessively saturated.
All of the above was pretty unscientific (I should know, I used to BE a Research scientist ) - but hopefully this gives you some idea of how easy it is to mix these inks - and how effectively you can darken a base colour with small quantities of the black...
