Why so many files? Python can easily support thousands of lines in a file.
If it's just one file any text editor can do a quick find-replace.
That said, it's easy to make some global ``red = 'red'``.
Some of these constants are shortcuts. Instead of writing slice(0, 16)

Why hide these things in a dict ``const`` instead of just making them
top-level variables in the module themselves? ``board_top = slice(48,
64)``

Or just use one file to keep things easier. But, yes, I agree a module of
constants is appropriate for bigger projects.
