Typically they're the quieter, black and white ones, but there was a piece ( Effingham II, 1966. Acrylic on canvas. 127 1/2 × 132 × 4 in.) in the show that used the most intensely vibrant colors that surely raise your heart rate, but cause a reaction for that reason. Below is a detail. I found it invigorating. What do you think?
