Daler-Rowney have worked closely with artists to develop a wide range of mediums in support of their colours systems, and offer a variety of products to cover the varying needs of today's artists. It was only relatively recently, in the mid-20th century, that acrylic colours were developed to offer artists a new, vibrant and exciting painting alternative. The versatility of acrylics and their immediate popularity soon led to the introduction of acrylic mediums, a range of products designed to enhance the benefits of acrylics and allow special effects to be achieved.
