: I also find this effect very displeasing. I have found that adding some copal concentrate in the paint overcome this effect (probably made with cold pressed oil?). Using mediums like maroger or Balsam/stand oil as a lubricant also counteract this effect. It effectively seems that the "suede effect" increase with paints that are not very oily, like holbein paints, for example. However, homemade paints grinded in refined linseed oil also shows the same effect even if they are on the oily side. So the type of oil is certainly the main factor.

As you say, the problem may be in more than one factor; it may be a combination of several factors such as stabilizers, prolonged grinding at too high pressure to obtain maximum pigment concentrations, AND the use of hot pressed oils. Taubes recommended the simple expedient of adding a few drops of a polymerized oil such as stand oil to the colors on the palette to eliminate the short qualitiy (ie. suedeing) of modern tube paints and produce a long paint consistecy. Perhaps that is all that is required
