Unione is similar to sfumato, but is more useful for the edges of chiaroscuro, where vibrant colors are involved. As with chiaroscuro, unione conveys the contrasts, and as sfumato it strives for harmony and unity, but also for coloristic richness.[5] Unione is softer than chiaroscuro in the search for the right tonal key. There should be the harmony between light and dark, without the excesses and accentuation of a chiaroscuro mode.[6]
