at a slight risk of being accused sexist....
Just drop a bit of pink/purple nail varnish on the outside of your tank ???
joke aside (sorry), I did a bit of matchy matchy once or twice
but now I tend to go with something that works & not bother tooooooo much re: matchy
yeah - it looks good if it marries up all sweet
but certain colours/styles can be restricted for choice
plus the purpley/pink Adept came with a silver Zlide but pink-ish drip tip
Sometimes a clash of colour looks beautiful & bold
but other times the range of choice means what matches looks good but restricts your choice
or your final choice you could be settling for second/third best setup if matchy takes priority
Pinky/Purple or bespoke colours will restrict your options I'm afraid
and even the "rainbow" coloured tanks that might have a bit of purple in them....
naaahhh that will look Fugly with all the other colours in there too
A black, silver or maybe gunmetal tank will a safe-ish bet
(or treat ya tank to a shellac manicure)
find something, easy to use, you can get on with, with good flavour that looks alright
don't worry toooooooooooooo much about the external colour/appearance if it works....
