Nothing has been more worrying, over my long wait, than colour choice.
Having ordered Ascot grey, I changed within the allowed period to the "opposite end": starlight blue.
I went for Ascot grey first as it is a sensible choice for sun reflection and ease on the eye. But then I kept looking at my deep dark green Phaeton and thinking how well it looked when polished up, and switched to the equally dark starlight blue, notwithstanding the heat absorption I will now suffer in summer (but perhaps a small benefit on sunny winter days).
Like so many things, you get used to what you have. Also both colours, and all the other alternatives, look well to me so I wonder why I was so stressed by the decision!
