It isn't much, granted and you MUST view in LyteBox at fully 100% (hit F key), to see these things...
If you look at the top edge of the chimney, there's a cyan/green edge.
There's a similar edge below the elbow of the chap partially in front of the chimney.
The key thing is they are equal and opposite across high contrast light/dark transitions heading towards the middle. CA is always worst near the edge of the lens' imaging circle, IOW, usually the corners.
The clincher (for me) is the chap in the lower left corner, his outline against the sky has both coloured edges, on opposite sides of his body and arms; left/right and above/below.
