Nice, I didn't know about this range! I'm curious about the blues
Here's a quick snapshot - sorry I don't have a swab of Visconti Blue for comparison, I packed it! (Moving home on Monday...)
The lighting's not the best, but I think it captures the colours *reasonably* well.
Barrier Reef Blue is more of a turquoise colour - in a wet pen, and on a less absorbent paper (I packed my Tomoe River!), it will sheen a little at the edges (reddish).
Sydney Harbour Blue, in my pen, is more of a blue-green than a blue-grey (as suggested by the website) - but I think that makes it *more* rather than *less* like the Sydney Harbour itself!
Will try and post some reviews once my desk is reassembled in the new house...
