    Sui Gouache, made by Illlustrator Sui, is opaque watercolor paint.
    While watercolor boasts its transparency and fluidity, 
    Gouache’s charm lies in its thick opaqueness with its calm color and matte finish.
    Uniqueness of gouache mesmerized me and eventually led me 
    to launch my own collection and write book about gouache. 
    Whenever I look at Claude Monet, master of color and light, ‘Water Lilies’ series, 
    I start to wonder, “How did he reflect such beautiful color?”
    To convey beauty of the color,
    I made paint that anyone can easily enjoy sensuous mixture of various color.
