‘Hope’ GTK+ theme gives your desktop a cold, wintery feel with its blue highlights and steely gradients.
Although Hope draws together elements from Ambiance, elementary and Impression GTK+ themes it stands a unique them in its own right.
It looks cohesive as a whole and by cherry picking the best of the aforementioned themes is somewhat like a ‘greatest hits’ of ‘out of your way’ designs.
