Who is known for his use of vibrant color and unusual perspectives in his paintings during the Mannerist period?

El Greco is renowned for his distinctive use of vibrant colors and unconventional perspectives, which are hallmarks of his style during the Mannerist period. His works often feature elongated figures and dramatic lighting that contribute to an emotional intensity. El Greco's ability to manipulate color and form allows him to convey deep spirituality and movement within his paintings, differentiating him from his contemporaries who adhered more closely to the balanced proportions and serene compositions characteristic of earlier Renaissance art. This dynamic approach to both color and perspective makes his work stand out as a significant contribution to the Mannerist movement.
