Janine van Herwaarden's work revolves primarily around color. Through her paintings and wall objects, she seeks to evoke a sense of joy—both for the viewer and for herself. The creative process plays a central role in her practice, with color serving as an essential element that makes the act of creating engaging, intuitive, and joyful.

She believes that color has a profound influence on our moods and emotions, shaping the way we experience the world around us.

Her paintings and wall objects are abstract, layered compositions that emerge from her imagination. They are inspired by the beauty of everyday life, nature, and ordinary objects. Craftsmanship has always been an important part of her life and continues to be a constant source of inspiration. She is particularly drawn to ceramics, pottery, textiles, crochet, knitting, and traditional techniques such as sashiko.

Knitting and crochet have been part of her life since childhood, with her grandmother serving as her greatest role model. Cherished memories of her grandmother's vibrant knitwear and the colorful patchwork crocheted bedspread she slept under during visits remain a lasting source of inspiration.

As a result, traces of patterns, textiles, and patchwork have become recurring elements throughout her work, reflecting both a personal history and a deep appreciation for craft traditions.
