Why Watercolor Provides a Suitable Medium for Color Observation
Different materials create different opportunities for observation
Colors and pigments can be explored through many different artistic materials. Each material follows its own production process, behaves differently during use, and reveals different aspects of color over time.
For the Color Archive, the material itself is not the primary subject of interest. More important is whether it provides conditions that allow changes in color and pigment to be observed continuously and documented over time.

Watercolor allows changes to remain observable
The production of handmade watercolor unfolds over a series of distinct stages.
From preparing the binder and combining it with the pigment to filling the pans in layers and allowing them to dry, each stage creates opportunities for observation. Changes in appearance, drying behavior, surface texture, and other visual characteristics can be followed throughout the entire process.
The making of the paint therefore becomes part of the observation rather than simply a step toward the finished product.

The same pigment can produce different results
The behavior of a pigment is influenced by more than the pigment itself.
Changes in the composition of the binder, the proportions of the ingredients, or the way the paint is prepared may alter the final appearance, surface quality, or drying behavior of the same pigment. These differences become part of the observation and provide additional information about the relationship between pigment and material.
Observation therefore extends beyond the pigment to include the conditions in which the pigment exists.

Small batches make comparison easier
Handmade watercolor is produced in relatively small quantities.
Working in small batches allows each stage of production to be observed individually and compared with previous batches. Differences that appear from one preparation to another become opportunities for further observation instead of being treated merely as variations to eliminate.
The production process therefore supports continuous documentation rather than repetition alone.

Observation continues after the paint is finished
The completion of a watercolor pan does not mark the end of the observation.
Once the paint is applied to paper, additional differences become visible. Variations that appeared during production may become more evident during painting, while others may only emerge after the paint has dried completely.
The observation of a color therefore includes both its production and its use.

The material serves the observation
Watercolor is not used because it is intended to represent all painting materials or because it is considered superior to other media.
It provides a practical environment in which pigments, formulations, and visual changes can be observed over extended periods of time. The material serves as a medium through which color can be studied, compared, and documented as part of a continuously growing Color Archive.
