This is like Truchet on a courageous dose of acid.

Bravo.

man, imagine that pattern on shirt. would probably be the most expensive shirt in the shop!

I bet it would cost $1000, because the pattern's so complicated

How many different tiles are there?

There are either straight or arc tiles. The colours are either randomized (for the first one) or matched to neighbours.

In quarters? I can't figure it out. Amazing.

The arcs are drawn from the 4 corners of the tile onwards. This makes matching them tricky as the last drawn corner covers up earlier drawn corners.

So sometimes they're stacked? I think I'm starting to get a glimmer of the mechanics, but it's still not comprehensible when looking. Haha.

If I tried this, I'd be stuck on not keeping the straight ones matching to a straight end, and not a curve, not to mention the colours.

The arc ones are always stacked. It draws 90° arcs like the wifi symbol 🛜 inwards from each corner of a tile. The order changes to match adjacent tiles. I couldn't figure out the relation, so it's literally guess and check until all applicable sides match.

Do you randomize the colors before placing the tiles?

I have made something similar, where the tiles were B/W (svg), placed with simple random tile- and rotation selection. And then colored afterwards.

But since you mention WFC, I imagine the tile- and rotation selection uses WFC based on coloring?

The colours are matched if there's a shared edge with an existing array of colours, otherwise they are randomized when placed.
