I prefer the older design where the ink colour is prominent. Switching to dark boxes with a small circle doesn't make a lot of sense to me. Also, the old box was very clear on what the content was intended for. I like that.
Herbin has interesting boxes. On top is a square showing the colour. On front is a picture showing what the ink is associated with. This is a really nice touch.
Waterman has a very utilitarian package design. You can't miss the colour as it's on the boxes' all six sides and it's repeated on the bottles too.
