Doy Kastilyo celebrates life’s twists and turns, where every color, line, or shape has a meaning and purpose beyond the surface.

Kastilyo's fauvist paintings create bewilderment, yet he insists that there are splashes of methodical madness in his vibrant and intense style, heightening emotions. His distinctive Pinoy Fauvism style incorporates vibrant, wild, and dynamic colors along with impromptu lines and his own unique expression, which is a characteristic attribute of everyday Filipino culture and way of life.

Kastilyo refuses to center his art on his persona, but like many artists, he aspires to make his art known worldwide. He seeks to provoke the audience or simply make them think differently.

More than that, he wants his art to create a ripple of inspiration among fellow artists, so that together, they will showcase the beauty of Filipino culture and traditions.
