My response from Mr. Gordon-Stewart:

Hi Clayton,
Thanks for the feedback, although I think you'll find that all of the Dolgnwot cartoons have had adjacent boxes drawn in the same colour.

Cheers,

Samuel

I only sent the email in response to the increase in frequency of this 'adjacent box' problem. Also, no thanks for the citing, but, we can't have everything.
