Customize console output color?

[AdamMc331]

I was looking at the console logs of one of my builds recently that had KtLint errors, and at first they didn't stand out to me. I have the color option on, but noticed that when we color things, they're gray by default: https://github.com/pinterest/ktlint/blob/master/ktlint-reporter-plain/src/main/kotlin/com/pinterest/ktlint/reporter/plain/PlainReporter.kt#L56

Against a black console, this doesn't really stand out to me. Other code quality tools like Detekt will output these using a sharper color like yellow.

I'm curious if we could change the color to something that stands out a little more against a dark console, or if the output color is something that could be customized?

An example of how hard this was to read:

Well it wouldn't be very plain then, would it? :)

I don't have strong feelings about this either way - you could easily write another custom reporter with nice colors, or this could be customizable...maybe by passing a color to the --color flag? e.g. ktlint --color="(255, 0, 0)" or something

I like that idea! I notice we already have a bunch of colors defined here: https://github.com/pinterest/ktlint/blob/master/ktlint-reporter-plain/src/main/kotlin/com/pinterest/ktlint/reporter/plain/internal/Color.kt

Ideally I could reference these, and maybe we can do --color="RED" and parse the color from that name. If no name is supplied, it could just default to the DARK_GRAY we already use.

I don't know much about how KtLint works now and it may take me a while to figure out how to implement this but I will try. If anyone sees this and knows a quick way to the solution feel free to take it from me. :)

Here's my take on that: #585
