Blue is the color of calmness and peace. It draws in and intoxicates. The strength of this color is as a rule underestimated. It creates precondition for deep reflection about life, calls to find the meaning and truth, it calls for not sensual but rather spiritual impressions. Now let's proceed to analyzing the center of the composition. There is an optical center in the middle - you will notice that the center of the composition, the major element will never be placed there, otherwise the scene will look artificial. The center of the composition will always be the most striking element, and the rest will just serve to make it more expressive. The artist may use various means to achieve this effect - the color contrasts, light and shade effects, size of objects and distance between them. Secondary elements are depicted with less detail and vigor - they have to bring forward the center, not block it. Notice the way your eyes travel the painting - intuitively you will start at the center and will proceed to the rest of the elements to refine the story. Rubber-base paints, which dry to a hard semi-gloss finish, may be used on concrete floors below grade, providing the floor is not continually damp from seepage and condensation.
Basically what you're looking for is a good, solid foundation of existing paint that is stable and still strongly bonded to the car. Many times an original factory paint job, even after decades will meet these criteria. Store your leftover paint in plastic Rubbermaid beverage jugs or other plastic seal-able containers. Paint left in the can always gets funny after time. Either the can isn't properly sealed of it gets exposed to extreme heat or cold. I like to store my paint inside where the temperature is controlled. First consider the size of the painting. The more impressive the subject, the higher the emotions it appeals to, the bigger it is. Religious, mythological paintings are often huge - their massive energy makes you shiver. It is pretty understandable with figurative paintings like Rafael's "The Sistine Madonna", and more subtle with color field paintings of Mark Rothko. People are often overwhelmed with religious tremor in the presence of his artwork, and the size factors in. Also, the subject often calls for larger canvases - battle scenes need space and cannot be fitted into a smaller painting, while some subjects will get lost unless depicted in a smaller size. In symbolism you do need to look for the hidden meaning, and it's absolutely pointless in pop art, op art, art nouveau or hyperrealism. Each style and genre sets forth its requirements, so brush up on the movement the artist belongs to before you proceed.
