During a recent band rehearsal I started a discussion about how I see chords as colours when I play. I don't actually see the colours in the physical world, but in my 'mind's eye' so to speak (I have a similar thing with days and months, and weeks and years are shaped.

Em is purple, D is brown , G is yellow, C is pillarbox red, Bm is blue etc.

Thus Kid on the Mountain goes purple-red-yellow-red etc.

Seems I am not alone with this according to the BBC website .

I am not sure this is what I have, but do any other catters experience this? I love it!
