Watercolor Paints Astra set 18 colors, 23.5 mm pans

Astra watercolor paints set with 18 individual pans, each 23.5 mm in diameter, provides a compact, ready-to-use palette for painting, sketching and mixed-media work. The dried pans activate with water to produce transparent washes and layered color effects. The set is designed for ease of use, portability and straightforward color mixing suitable for students, hobbyists and practicing artists.

Advantages

The 23.5 mm pans are individually seated to allow selective replacement and controlled use of each color. Dried, water-activated pigments give consistent transparency and predictable behavior when diluted; this supports layering and glazing techniques. A compact arrangement of 18 colors means a broad, balanced range of hues while keeping the palette portable and convenient for fieldwork or classroom use.

How to use

Activate a pan by lightly wetting it with a brush or adding a few drops of water to achieve the desired intensity. Start with a small amount of water for more saturated strokes and increase dilution for lighter washes. Mix colors on a palette or directly on paper; allow layers to dry between applications to preserve transparency and prevent unwanted lifting. Clean brushes between colors to keep hues pure.

Usage recommendations

For best results, use heavier-weight watercolor paper (minimum 200 gsm) and quality sable or synthetic brushes. Test color mixtures on a scrap sheet to plan values and chroma before applying to final work. Store the set in a dry place and close the case after use to protect the pans from dust and moisture.
