The reasoning here is simple. Every color in the visible spectrum can be assigned a number based on a luminosity scale (a scale from light to dark) from 0 to 9 where white is 0 and black is 9. Now suppose that the brown you are trying to cover has a score of 8, and the yellow paint you want to apply has a 4.
Is the light neutral, sharp, mystical?
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.
Suppose it rains while you're working? Vinyl paint dries fast - as quickly as 10 to 30 minutes - and will withstand a shower after that time. It takes another 12 hours to "cure," by then forming an exceptionally tough, long-lasting film that stands up well against weather, sun, salt air and factory smoke.
Another popular color wheel called the Munsell color wheel, is slightly more involved. Instead of 6 basic colors, the Munsell wheel consists of ten colors: red, yellow-red, yellow, yellow-green, green, blue-green, blue, blue-violet, red-violet and violet.
If you have a timber floor that's not particularly attractive or is made from a patchwork of old and new wood, paint makes the perfect disguise. There are plenty of choices - all the colours from Farrow & Ball are available as floor paint and Nordic Style offers an elegant selection, too.
PAINTING YOUR CEILING TIPS. · If you are painting the entire room, it is best to paint the ceiling first! · If you are using a paint roller, maneuver your arms in series of diagonal swaths (forming a letter M). Fill in the open areas by cross rolling. · If you are using a paintbrush, apply the paint in short strokes towards the unpainted area, known as "wet to dry." Then brush back into the area you just painted for a smooth surface. · If you are painting your ceiling, remove light bulbs, chandeliers, fluorescent lights and fixture covers. · Paint trim first, including edging around the ceiling, molding, and trim.
