I used to own a JVC KD-V35 cassette tape deck. The level meters and spectrum analyzer are blue-green and red: https://www.cassettedeck.org/jvc/kd-v35 <https://www.cassettedeck.org/jvc/kd-v35> Note the third level meter in between the left and right peak level meters. IIRC, it was was weighted in some way, possible RMS or something imitating the ballistics of a true VU meter. After I had a number of problems with it the dealer replaced it with a newer model, the KD-V400: https://www.youtube.com/watch?v=ANeTJtokq9I <https://www.youtube.com/watch?v=ANeTJtokq9I> They switched to backlit LCDs which were much slower to respond. OTOH, the 400 was actuated entirely by motors instead of solenoids and had a number of improved features. I have two of them sitting here along with the old boombox that sat in the back seat of my stereo-less car(s). Too many memories of too much great music to get rid of that one even though the piano keys have become so brittle that they snap off if pushed.
