Depends on what the color indicates. If it is like furuno, where target
strength is indicated by color then there is some usefull information
there, but for my money color is an expensive option. I would rather
put my money into a bigger antenna, and a bit more Tx Power. That buys
more sensitivity and better target resolution, which is why you have a
radar in the first place. In the old days, (before Loran and GPS) radars
had a dual purpose. We used them for naviagation, and position fixing.
(navigation=not running into things that move around position fixing=
not running into things that don't move) In todays world, radars are
used more for navigation, and much less for position fixing, as GPS does
a much better job of position fixing. Better to see moving stuff
farther away, than after it is under the bow.
