37: Colour and Style Q&A: Transitioning Colour Palettes, V Shape Column of Colour and Salt and Pepper Hair how to select colour schemes

How do I go about transitioning from a brighter palette to a more muted one without feeling faded out?
V shape body – should I wear an inner or outer column of colour? Also, if not wearing exactly the same colours, how different can the top and bottom be?
With salt and pepper silver hair, brown eyes and fair freckled skin – can I wear only a monochromatic scheme or neutrals plus a colour?
