But why they are grey-faded?

Grayed-out icons and numbers give the impression that the buttons are disabled, which is poor UX. The fact that this also results in poor color contrast in your proposal makes it a problem for accessibility as well. I think the proposal itself is fine, but I see no reason not to use more visible colors.
