The range of 40 colours are chosen according to mass tone (colour from tube), undertone (bias of colour when in a thin film), colour strength, relative opacity and the character of the pigment itself. The resultant colour spectrum ensures the largest number of colours can be mixed.

The Cotman Water Colour range has a more uniform consistency than the Artists' Water Colour range and this benefits beginners as there is less to learn about each individual pigment. The Cotman Water Colour range also relates to the Winsor & Newton Artists' Water Colour range, this enables artists to use colours from both ranges with minimal adjustment to their technique.

New Gamboge - pigment change Originally produced using Gamboge, a coloured gum from the Garcinia plant, Artists' Water Colour Gamboge was discontinued in 2005, due to its toxic characteristics. Its replacement was a different shade, due to the pigments available and renamed New Gamboge. Due to the above pigment discontinuation, New Gamboge, in both Professional Water Colour and Cotman, has been reformulated once again and, with advances in pigment technology, the colour is much closer to its original namesake, delivering greater authenticity within the spectrum. The pigments have changed from Nickel Dioxine PY153 to Quinacridone PR209 & Azo Nickel Complex PY150

What do you get when you mix pigment, wax, and oil? You get a pigment stick of creamy soft texture also known as Gelatos. Gelatos are acid-free, odorless, and water-soluble. They can be used by themselves or combined with water through a series of techniques to create a watercolor medium.

Gelatos with mixed media art
Gelatos quality pigment is resistant to fading under normal lighting conditions and is compatible with most other acrylic mediums. The easy twist up design of Gelatos makes them easy to maintain and store and their solid opaque color is perfect to cover large surfaces.

Gelatos can be used on paper, cloth, canvas, wood, and fabric. We recommend using a thicker paper such as watercolor paper and using a sealant when working with fabric. Gelatos are also great to use when journaling in your books, notebooks, or bibles, and their vibrant colors look great against dark colored surfaces. With such versatility, it can be hard to know where to start with your Gelatos. Here you can find a handful of techniques to gain a better understanding of this medium.

(Note: when using Gelatos with fabric, treat your work as a piece of art. We do not recommend laundering any items to which Gelatos have been applied.)

Blending Gelatos is a great technique to add color and dimension to your work. Combine colors together to create new colors and blend multiple colors together with your fingertips, a cotton swab, water, or a blending tool. Another technique to try on your Gelatos is edging. With the edging technique, create a distressed or grunge effect by drawing color along the edge of your paper then blend to fade color inward.
