The paints may be applied by brush or spray; the small spray attachment for vacuum cleaners is very convenient, especially for painting radiators. Like this, it will actually take quite a while to reach a number that is close enough to the yellow color you've chosen that you can't tell any difference (and mathematically, you will never actually reach an average of 4!) If you decide to do your own body work discuss it with the paint shop first. They'll probably have recommendations on the type of primer you use. Some brands will be more compatible with their primers or color coats. The rule of thumb is to stay within the same brand of paint, both for prep and color. Even the cheapest paint shops typically use a brand name on their intermediate and higher paint jobs. Find out what it is and use the same brand as your primer coat. This will ensure you don't create adhesion problems for yourself down the road.
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. The second part of preparation is surface prep, it addresses covering the surfaces you do not want to get any paint on. A little plastic sheeting will go along way to keeping paint off of floors, window coverings, handrails, cabinets, counter tops, etc... And, if you are not confident with your ability to paint a straight line next to door casing, baseboards, cabinets or hardware protect these surfaces using masking tape. There are two basic types of masking tape white/yellow and blue. The white tape sticks to surfaces better but, can pull off finishes on cabinets or stained woodwork. Blue tape usually will not pull off finishes but, does not stick as well, this will probably be the tape to use for most applications. Always wipe down or dust the surface you will be masking to assure the best tape adhesion possible. If you use blue tape you may need to re-rub down the tape before painting next to it, only mask off areas with blue tape that you will be painting for a given day. With either tapes, do not assume the are a force field that paint will not penetrate, use them as a reference and dry brush the paint next to the edge of the tape and avoid soaking the edge of the tape with a lot of paint, this will cause the paint to "bleed" through giving you an undesired look. If you will need to apply multiple coats of paint, on the first coat, paint as close to the tape as you can, not really getting paint on the tape. With the second coat or a one coat application, you can use the tape more of like a paint barrier and get a little more paint on the tape if you immediately remove each section of tape after painting the section, this will keep the paint from sitting on the tape and "bleeding" behind it. Also, if you get a lot of paint on the tape it is not good to let the paint dry on the tape because some paints (especially the glossier paints) will peel if allowed to dried, with the tape when it is pulled off. White tape should not be left on for longer than a couple of days and I suggest not leaving it on more than a day in areas that receive long periods of direct sunlight. Blue tape can be left on for days, if it will stay on, there again it does not stick as well and may need rubbed down again immediately before painting up next to it. Will the color fade? Now this is a very broad question with various answers. Hair color fading is due to many factors. First of which is, the ability of the hair to hold hair color. We call this porosity. If the hair is overly porous it will have a problem holding hair color. There are ways a stylist can usually alleviate this problem. Once in a while the hair is so damaged it absolutely impossible for the hair to hold color. Your stylist should always have the skills to evaluate these situations, and recommend certain conditioning treatments to bring the hair back to a normal porosity. Color can make a big difference in your life. I know from experience. Before I learned my right colors, I had a closet full of right and wrong colors. Of course, the colors did not work together and definitely did not coordinate. I had no idea of the difference that coordinated colors can make. Further, I had a drawer full of lipsticks some with gold undertones and some with blue undertones.
