We should definitely try to support customizing colors in the output similar to how ag does it. Currently they support 3 color customizations, as per this issue:

• --colors-match
• --colors-path
• --colors-line-number

Implementing the part where we set colors based on an argument is not particularly hard (just a matter of translating user input to term::Attr enums). Parsing input in the bash terminal format like ag does was not difficult to implement. However, this limits Windows usage because we don't have an easy translation between those colors.

How should we go about supporting these color customizations for both Linux, Mac and Windows?
