When using a puTTY or terminal window to a Unix server some people like to set the colors of the text or background, some people dont.
Sometimes I like to set the text color to be like to old school Amber monitors. To do this I use following color settings
RED: 255, GREEN: 128, BLUE: 0
If also found a very nice blue color once that I use occasionally.
RED: 5, GREEN: 150, BLUE: 229
