When I look at the log in tortoise why are some of the files for each commit highlighted?

Question

I am trying to search through history on a folder with tortoise git. I found what I want but annoyingly I cant figure out what the difference between rows that are highlighted and rows that aren't for each commit. It's tricky to explain but here is a screen shot...

You can see the highlighted rows are more red, why? (Apologies about the obfuscation it's a sensitive project).

Thanks

When you show the commit log in tortoise, it shows the entire commit for all paths. What's happening is you did a show log on a sub directory, so tortoise is highlighting the files that were affected in that directory.
