Thinking about a dash light upgrade. Your thoughts?

The factory instrument panel lights in my 1974 Duster are pretty dim, even when the rheostat is turned all the way up. Has anyone out there done the LED upgrade, where you simply plug the LED bulbs into the existing bulb holders on the back of the instrument panel? There are several colors of white available, so I wouldn't want a very starkly white light as it wouldn't match the off-white color of the radio and heater panel. What color did you use? Were you happy with the result? Is your instrument panel brighter at night now? All ideas welcome - thanks!
