DIGITALIZING NATURAL DYE COLORS
NATURAL COLORS IN THE DIGITAL AGE
Natural Colors in the Digital Age
According to Cath Sleeman’s 2020 research at the Science Museum Group Collection, modern designs are increasingly monochromatic, only using a small part of more than 16,000 colors stored in digital systems. From this contrast, VAN•HOA, as a creative studio, poses a question: As this monochrome trend has been reigning with the industrial revolution, Is there still room for natural colors in the design world?
The Trend of Natural Fabric Dyeing in Vietnam
As a tropical monsoon country, Vietnam enjoys a vibrant natural ecosystem that the Vietnamese benefit greatly from. The local people have developed a lifestyle closely connected with nature, particularly in the practices of natural fabric weaving and dyeing.
Nowadays, as the sustainable lifestyle and Vietnamese handcrafted fabrics gain more support from mass, the trend of natural fabric dyeing is gradually making a comeback from new business and preservation groups. Even data on natural fabric dyeing is being refined through the research of the younger generations, notably Nguyễn Đức Huy, the founder of the Đông Phong - a Vietnamese traditional restoration clothing brand. In this collaboration with Đông Phong, VAN•HOA aims to preserve the colors of Vietnam's natural dyes through a digital color palette system based on naturally dyed fabrics from Đông Phong.

About Đông Phong and the Digitalization of Natural Dye Color Data
Originating from the question 'Who am I? How is my culture different from other cultures?' while studying in Germany, Nguyễn Đức Huy, the founder of Đông Phong clothing brand, began his passion for ancient clothing. After returning to Vietnam and spending time learning indigo dyeing in Sapa, Huy started practicing natural dyeing to pursue a sustainable lifestyle and utilize naturally dyed fabrics in making Vietnamese ancient clothing, aiming to replicate the old colors that once presented in Vietnamese history while steering Đông Phong's products away from fast fashion.
Over time, Đức Huy has built a data system for his naturally dyed fabric samples in physical form, accompanied by detailed notes and fabric dyeing formulas after numerous studies.
Wishing to spread the research values of Huy and Đông Phong, as well as increase diversity in the applications of this color palette, VAN•HOA proposed and was agreed to digitalize and systematize Đông Phong's naturally dyed fabrics data.
Natural Fabric Dyeing Process
Coloring Materials
The natural dyes at Đông Phong are created from various plants and insects from nature. These materials are usually dried or crushed, except for indigo which needs to be fermented and processed into a paste.
Dyeing Material: Fabric
Depending on the structure and surface of the fabric, there can be different effects and shades after dyeing. Currently, Đông Phong is collaborating with traditional craft villages to produce various types of handcrafted silk. However, in natural dyeing, Đông Phong only uses two types of fabrics - one made from 100% raw silk, and another combined warp threads of boil silk and weft threads of raw silk.
The reasons to choose these two types of silk largely depend on their dye absorption properties, stiffness, and sheen. The 100% raw silk fabric resembles an Vietnamese ancient fabric called “Sa” and could absorb dye better. Meanwhile, the warp-raw-weft-boiled silk fabric has a certain sheen and softness from the combination of the two types of silk.
Additives: Dye Fixatives
According to Đông Phong, the most commonly used dye fixatives are alum, including alum, copper alum, and iron alum. For materials that already contain tannins, such as guava leaves and tea leaves, alum is not needed.
Natural Fabric Dyeing Process
Step 1: Prepare Materials
The dye materials are pre-processed by drying and then cutting into small pieces. Indigo, as the only exception, is processed into an indigo paste.
Step 2: Make Dye Solution
Depending on the material, either a cold or hot dyeing method can be chosen. For cold dyeing, soak the dye materials in water to extract the dye. For hot dyeing, boil the materials and then filter the residue from the dye solution.
Step 3: Pour The Dye Solution Into The Dye Vat
The dye vat is sized to fit the fabric width. After making the dye solution, put the dye materials into the vat then pour the dye solution in.
Step 4: Add Alum To The Dye Solution
Add the dye fixative to the dye solution. To save time, soak the fabric in alum once before putting it into the dye vat.
Step 5: Dye The Fabric With Roller
Spread the fabric evenly on a roller and rotate the roller so that the fabric is uniformly exposed to the dye solution. For smaller pieces of fabric, directly submerge them in the dye solution and knead by hand.
Step 6: Rinse The Fabric
After dyeing, rinse the fabric with clean water 3-4 times to remove excess alum and dye solution.
Step 7: Dry The Fabric
Dry the fabric on a hanger, ensuring it is spread straight without folds.
Step 8: Recycle The Remaining Materials
Since all the used ingredients are natural, the remaining dye materials can be used as fertilizer or dried into firewood. The leftover dye solution can also be used for irrigation.
The Digital Color Palette
Chromatic Circle
Organizing the Digital Color Palette
After thorough research, VAN•HOA decided to organize the digital natural dye color palette according to the hue circle rule based on the common characteristics between Đông Phong's dye palette and the RYB (Red/Yellow/Blue) color system.
The order of the dye colors is divided into the hue circle levels, including:
-
Primary colors - 3 color pigments that cannot be mixed or created by any other color combinations.
-
Secondary colors - Color pigments created by two primary colors.
-
Tertiary colors - Color pigments created by one primary color and one secondary color.
-
Neutral colors - Color pigments that are almost impossible to trace back to their base color or color temperature, such as black and white.
In each color palette, the colors are further classified based on the dye materials, arranged by the intensity and value of the natural dye colors after digitalization.
