I would say outside due to the fact the light blue line crosses over the green line near the center. Had they been solid colors, it would go either way.

The illusion is about whether the corner with the star is the closest to us (hence the star is outside the box) or the furthest (and the star - "inside").

Very nice, except for that error in the light blue.

I'm sure I didn't make that mistake with the blue? Perhas an error in transmission?
