Converting a Color object to its string representation

[Scott Palmer]

I agree. I was going to write pretty much this exact email, but you beat me to it.
I was implementing some user-configurable colour customizations in an application and needed to do it with style sheets, along with something that reads colours along the lines of what the new platform preferences API does. 
I make a base64 data URL from a dynamically generated style sheet to avoid writing temp CSS files to style the app. 
I also needed to do this to work around the style sheet having higher priority than programmatically set colours as per my misunderstanding in https://bugs.openjdk.org/browse/JDK-8317434
So I see value in having Color implement something like this.
