Yellow color is sunny and light. Historically this color symbolizes gold and wealth, and in the East it is a symbol of eternity and greatness. This color creates optimistic and bright mood and goes together greatly with the other colors of the interior. At the same time the warm sunny tints never carry a negative charge. Yellow color creates an impression of lightness and joy. It frees you from the weight of worries, problems, and limits. This color is hope and expectation of big happiness in its multiple forms starting with sex and going up to some philosophical and religious outlooks. Building a monochromatic theme simply uses a single color in graduating shades like cream, beige and brown. It is hard to go wrong with this color palette, so everyone can use it successfully. But unless variations of the one color used are handled with flair, this can be an unexciting look. Materials and their application, every paint manufacturers paint will vary. If you are freshening up old walls and painting back to the existing color, the product doesn't have to be high end or have good coverage. If you need to paint a dark color over light color or light color over dark, you may want to consider purchasing a top quality paint to avoid multiple coats. I suggest Valspar, Pittsburgh or Benjamin Moore top of the line wall paint. These brands work well for straight out of the bucket use and are application friendly. Sherwin Williams is not my first choice because the coverage is poor and you will have to apply multiple coats but, it does apply, fluently. If you find a product does not apply well, maybe it is to heavy and/or sagging on the wall, you may need to thin the paint with a little water, this will reduce the coverage but make the paint flow better and lay down nicer on the surface. I do recommend latex paints for all applications, these days a good high end latex is as good as oil paint and your tools clean up much easier, it will also be less harsh on the respiratory system. The only situation I recommend oil paint, is as a primer/stain blocker over stains that "bleed" through the paint. You can get a stain blocking oil primer in a convenient spray can and spot prime any trouble areas before painting and in the case you need to prime all of the wall due to smoke or water damage, I recommend getting it in gallons and rolling it on where the stains are present. Don't forget proper ventilation and/or a respirator when using the oil based primers!
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. Technical advancements are constantly being made to improve the life span, durability, wear and performance of exterior paints. The Akrylatfarg range at Ray Munn, for example, is an environmentally sound water-based option. Can you feel the rhythm in repeating some color or combination? Painting ceiling does not require premium paint. You can use flat $15 to $20 ceiling paint. I use Sherwin Williams PRO-MAR 200. Painting ceiling requires a lot of physical work and plenty of drop cloths. If you are not up for the challenge or have very high ceilings contacted a professional will prove to be a smart move.
