I've been to New England many times during the months of September, October and November amd am thus aware of the spectacular Fall colours (should that be colors ?) that occur there at that time of year. You don'thave to look that hard. And if the light is good ( and it is frequently ) the word "spectacular" doesn't do it justice. Whilst I'm sure there are similar colours to be found amongst the foliage in Autumn here in the UK (can someone please tell me where?) I have yet to find any ..... but late Autumn was very much in abundance in Green Park (it is in cental London) a few days ago. Bright sunshine, blue skies and at 16 degrees C, almost a warm day.
Almost a two tone park - green and brown - with the brown just about dominating the colour palette. And muted, despite the sun light. A rather different colour experience to Fall in New England, but just as enjoyable,
