"You could spend hours wandering through the halls of the National Gallery, but if you only go to one room, it should be the hall devoted to the paintings of Irish artist Jack B. Yeats. The vibrant colors of his paintings are unexpected and striking, and it’s fascinating to see so much work from one painter in a single space.
