Puzzle #174: Trio Cut

This is the second practise puzzle for this year's UKPA Open.

I saw this type the first time in the No Numbers test at LMI. I have good memories of it as that's the only test I have ever won. This puzzle is definitely the harder puzzle. The first one I played around a bit with how the type worked. For this one I tried to find a bit more tricky an opening and path. I think it worked out well.

Rules:

Colour some cells so that they form triominos. Each triomino must be cut twice by a black border. Different triominos must not touch each other by an edge. Each black-bordered region must contain exactly three coloured cells. Cells in the same region may belong to the same triomino.
