H. VAN TEMPERA  Because mood or feeling are of primary importance, H. Van Tempera uses many approaches; semiabstractions to best show rain reflections on a city summer evening; subtle color in a foggy New England scene; bright color as thoroughbred horses, racing cars, polo ponies speed by in flashing light . . . impressions . . . captured by the artist in determined brush strokes and thick palette knife areas of color. Her figure drawings in oil are creative and sensitive.
