A few days ago, to learn to play music, I bought a keyboard (Yamaha, EZ-30). It has lighted keys and all light red. It somehow felt wrong that all keys light up red.

If A lights up red, then C should light up yellow - that's how I would think (may be I am biased because of my inclination toward physics - red is low frequency, yellow is higher frequency).

My question: is there a standard coding of colors for the musical notes (like that of a resistor) or am I just thinking non-sense by thinking it in terms of colors?

I also think that since my keyboard is touch sensitive, a hard A should light up brighter than a soft A.
