>>10742934Sorry for the delay mate, and for how crude the paint mixing test is.
I went through my paint collection, and pulled the closest relevant clear paints. They're all water based acrylics since they're from my warhammer days so they're not fit for customs, but they're close enough to test the colour theory at least.
No mixture of the clear reds and blues I had resulted in any purples, just various shades of unappealing blue-black.
When testing the violet ink, the closest I got to desaturation is by mixing it with a pure orange. Using any of the Yellow ink resulted in an unpleasant redness to the result, and any of the Lemon resulted in an unpleasant brown tone.
