Green, Red, White and Gold: How the Leaf Archive Is Structured

How the four material groups, product names and material codes guide you through our Kratom Leaf Archive.

Philipp Kaufmann3 min read

Our Leaf Archive comprises eleven dry, finely ground kratom leaf powders for creative and craft experiments in the studio. For clear selection, the range is divided into four material groups: Green, Red, White and Gold. Each material also carries a product name and material code.

The groups organise the Leaf Archive. Product names serve to identify materials within their respective material group. Neither the group nor the product name is a promise of colour, origin or quality, nor a standardised colour designation. The material profile offers guidance. Product images show the packaging and available bag sizes; they are not a binding colour reference. For colour impression, grain and natural variation, your own working sample on the intended surface is decisive.

Eleven materials in a fixed order

The Green material group includes Green Bali SG, Green Borneo SGMD and Green Sumatra GD.

Red includes Red Bali RMD, Red Sumatra RD and Red Borneo RB. Red does not mean that the leaf powder appears red.

The White group contains White Borneo WMD, White Sumatra WD and White Bali GW. White promises neither white powder nor replaces a white pigment.

Gold includes Gold Borneo GOMD and Yellow Borneo GOD. This group, too, is not a promise of a golden-yellow material colour.

Product name and material code serve clear identification. For selection, we recommend: open the group, read the material profile, check the available bag size, and make a small working sample on the intended surface before undertaking larger work.

Not a classic four-colour system

Green, Red, White and Gold are neither a pigment standard nor four paint pans. They do not automatically produce green, red, white and yellow. Differences between leaf powders are more likely to appear in lightness, warmth, olive content, grain and texture. Separately identified artist pigments are needed for clear red, yellow, blue, white or black.

A simple material study can be made with water. Water moistens and disperses the leaf particles, but does not fully dissolve them or permanently bind them to the surface after drying. There is no blanket mixing ratio; begin with a few drops and work gradually.

If adhesion is to be part of the experiment, a suitable artist medium may be tested on a separate field according to the manufacturer's instructions. Binders and artist media are not included in our Studio Sets. These contain only dry leaf powder and the paper and brush products specified for each set.

In the material journal, concrete observations such as “light sage”, “muted olive”, “neutral khaki” or “warm earth tone” are helpful. They describe only the visible sample and make no promise of a permanent colour.

Note: Kratom leaf powder is not a food product and is not intended for human consumption. Follow product, packaging and manufacturer instructions; store dry, protected from light and out of the reach of children.
