Holbein Duo-Aqua Oil is an artist quality watermixable oil paint made with water-soluble linseed oil. To make DUO identical in every respect to its traditional professional grade cousin, Holbein developed a unique additive which works as a surfactant, any residue of which loses its effectiveness once the oil color is dry. 

These paints have a uniform drying time, and will hold brushmarks and dry to a lustrous sheen like traditional oils.


If you wish to alter the consistency, drying time, and transparency of your Duo Aqua Watermixable Oils, you can use Holbein's Duo Aqua Mediums.

If the artist does not wish to use water, DUO may be used as a traditional oil color and the result will be the same. DUO blends and mixes naturally with traditional oil color and traditional oil mediums although water solubility is lost if traditional oils or mediums exceed 30% of the mixture. DUO is not classified as a water base color, like gouache, acryla gouache, watercolor or acrylic, but all these blend perfectly with DUO while wet (add a few drops of water when blending with acrylic).



  • Drying time is comparable to traditional oil straight out of the tube (no water/mediums).
  • Water Will matte down the surface when mixed with DUO, like turpentine does to oil.
  • Quick Dry Medium or Painting Oil is ideal for glazing.
  • Traditional oil mediums may be used, but mixture will lose water solubility.
  • Traditional oil painting techniques apply for DUO (fat over lean).


This Standard set provides you with 12 standard colors in 20ml tubes and a 50ml Permanent White will allow you to started painting with DUO Aqua Oil Colors.
