sure, obviously... but in normal use they are gray. I use, and have used a lot of software and I don't remember one that has an interface, for the most part, gray. Maybe that's why those to whom I recommend Xnview and MP, tell me they prefer the first. The font is slightly different, I don't know how to explain it but if you enlarge the photo I posted, you'll notice it. The icons in Xnview are almost all colored... in Italy they say that "even the eye wants its part"
But the icons themselves, in my personal opinion, are not really beautiful, I don't understand that shade of purple and the icons are anonymous, they are cold.
Then mine is really a piece of advice on a trifle, your program is fantastic and you might find my criticisms ungenerous, I assure you that it is not so
thanks!
