Cold water paints of the casein type may be applied either directly to a plastered surface, or the surface may be first given a coat of primer-sealer to equalize uneven suction effects. The same is true of resin-emulsion paints, with the recommendations of the manufacturer of the product being given preference in case of doubt. Since resin-emulsion paints usually contain some oil in the binder, they should ordinarily be applied only to plaster which has dried thoroughly.
THE NARRATIVE. First look for the narrative, simply describe what you see. Who or what is depicted, what's going on? If you see people and things, the painting is figurative; if you see lines and splashes - go for non-figurative. The name of the painting might come in handy, especially when it comes to Dali. What seems to be more important for the artist - representation or expression? Compare the paintings in the styles of hyperrealism and expressionism - you can always tell if the images look idealized or expressly distorted. Notice the feelings you get looking at the painting, the general impression produced by the entire painting and its elements - later you will dig deeper to understand what inspired those emotions. There is a reason why you like one painting more than the other. Your taste in art is as unique as your taste in food or clothes, inspired by your background, upbringing and even professional expertise.
Primitivist (naive) artists depicted objects in a solid monumental manner, as seen by a child who perceives the world as a whole, without analyzing it and breaking into unnecessary components.
Is some color dominating?
Practically every manufacturer has a "color system," a fat book of color chips with instructions for duplicating each chip. This is accomplished by intermixing cans of colored paint, by adding a concentrated color to a can of white or colored paint, or by adding concentrated color or colors to a can of neutral "base" paint. And for those who don't want any guesswork there's the Color Carousel that mixes the paints right in the store. Whatever the method, the result is a range of colors such as no amateur painter has seen.
Purple is the most contradicting color, to start at least because it consists of two antagonists: hot red and cold blue, ice and fire. It is the most mysterious color. It was the last color to emerge in art. Purple has a lot of other shades that are less rich and more lightened and muted: starting from light-lilac and going up to ashy gray-purple, which can give the interior a certain style and exquisiteness.
Colors that are equally removed from a reference color are triadic colors. Since these color schemes can become too intense, unless they are very toned down, they are very problematic to manage. This color combination works well in a child's room, and it can be used effectively in a kitchen.
