On a modern type like the 777 there is an easy way to do it. You can call up the checklist on the screen and it marks everything that's "done" as green. So essentially you press the button, and all should be green.

That is better.

One thing they learned with airplanes is to set up the gauges so that when things are good, the needles all point in the same direction, regardless of what they were measuring. This made it easy for the pilot to scan the instruments. Later they added green, yellow, and red indications so an out-of-normal indication showed yellow, and really bad showed red.

Something car manufacturers still haven't cottoned on to.

For racing applications it's pretty common to have a multicolor LEDs as backlight for your gauges so your whatever gauge turns red when the reading is bad.

For normal cars the goal is totally different. They want to give you the minimum information needed to operate the vehicle and only alert when something is critically wrong. This is why proper oil pressure gauges went the way of the dodo in most vehicles.
