"I find that acrylics dry very fast - which is supposed to be its charm; however, I find that because of that quality they don't blend as nicely as the oils. The oils, for one thing, are softer and more flexible than the acrylics. Also, the colors are brighter with oils"

In this quote, artist Boris Vallejo is going over the differences between acrylic and oil paints. He notes that acrylics have the benefit of drying quickly, which is typically viewed as a favorable quality. However, he personally discovers that this fast drying time can make it hard to mix colors efficiently. On the other hand, he praises the softness and versatility of oil paints, which allow for more smooth mixing. Furthermore, Vallejo believes that oils produce brighter and more dynamic colors compared to acrylics. In general, he seems to choose the qualities of oil paints over acrylics in his art work.
