Chen feels that leaving white space is more difficult to master than the actual artwork, because all that space can easily end up looking excessive, or even downright vacant. That is why he is so careful about blank space. Besides, white and black are two of his favorite colors.
他認為，在設計上，留白的技巧比圖像更難，稍不留心，就會給人「大而無當」，甚至「空洞」的感覺，因此他很謹慎的處理留白，而白色與黑色正是他鍾愛的顏色。
