Which is better, #fff or #FFF? [closed]

Question

Which is better to define color?

color:#fff; 

or

color:#FFF; 

?

I like #FFF because it catch your eyes' focus faster than #fff. But PS returns lowercase, so I was wondering if lowercase hexadecimal is better than uppercase. Why this thread closed? o.Oa

Answer 1

It depends what colour you want. #fff is 'white' and #FFF is 'WHITE'. Your choice.

Answer 2

Neither;

color: white; 

In all seriousness, tho', it doesn't matter so long as it matches the general design of your site. (For example, SO or FB should use #FFF, while, say, Apple would use #fff. Matches the rounded corners better, you see?)
