\cc @zetashift what do you think?

IMO it would be better to make the selection background brighter rather than make the cursor and selection dimmer. The dim modifier turns down the contrast enough that it can be hard to read the selection contents

I've played a bit more with colors, I feel like sumiInk6 might be to bright overall, so I've updated the PR to use sumiInk5. Unless you feel strongly about it, I'd go with this one.
