[Feature Request]: Background Colour Configuration

[harrisward]

What would you like to happen?

Would it be possible to change the colour of the Hop UI background using a colour picker?

Would be even better to define a colour per Project / Environment. (Red for production, blue for development etc)

@hnasva, this is the coloring in 2.4 and 2.5-SNAPSHOT on Windows

White background for the dialogs is fine but the lite gray on the canvas area do not put in evidence the icons that are gray too. I think that a white coloring for the canvas area would be better too.
