I don't believe I've seen a pair of brogues like this pair from W. S. Foster where the leather has been left essentially uncolored, except in photographs, and then only twice. It may be the ultimate specialty shoe, too light in color for wear except in summer and, because of the limits that seasonality places on their usefulness, available only bespoke.
It would befit the man who owns these shoes to live in Positano, where his summer wardrobe consists of linen suits that he changes twice a day.
A mid-day change is good practice for linen trousers as well as suits, and that's a reason an elegant man might own more of each than may seem necessary to the casual, non-linen wearing, observer. My advice is that if there are any linen suits in a wardrobe they should be in multiples of two. Or, if it's not practical to change mid-afternoon, it's equally good form to disappear with a clothes steamer for fifteen minutes. Which is yet another reason why linen suits are less than ideal garb for office wear.
Of course, the man who owns these shoes is unlikely to spend much time in offices anyway.
