Reading also needs good visual perceptual skills. Shape perception allows us to recognise the similarities and differences in the shape of letters. Figure-ground perception is needed to be able to see the separate words on the page and the separate letters in the words. Spatial perception allows us to see where one word starts and another ends and which way round a letter must face.
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.
You can put it around a room and probably follow immediately with the finish coat. It can be applied with brush or roller.
Water-thinned rubber-latex paint is already an old reliable, though it is only about 10 years old. It accounts for a big percentage of all paint sold and is still the most widely available of the easy-to-use finishes. One new type is a combination vinyl-rubber paint that is said to do a better job on interiors than either vinyl or rubber alone because it dries faster, lasts longer and has less sheen.
Step three: go online and study the basics of shadow and light. It's a visual thing, and too complicated to talk about here. But once you see it, it'll come to you quickly. Simply Google "shadow and light in painting" and the basics will come up. Once you know these rules, you can apply it to any shape, any form, any painting. And it'll make you keenly aware of shadow and light on virtually any object on earth. It's what makes a painting three- dimensional and expensive looking. You can also buy art books on shadow and light at any bookstore. But make sure you sit down for a couple of hours and study it. It will come quickly to you, I promise.
The leading brands now flag up paints with lower VOCs and produce paints that are virtually odour-free - the Breatheasy range by Crown is one example. Most leading brands now produce high-quality water-based acrylic paints which outperform the older technologies of vinyl and oils.
Always use a sanding block for flat surfaces. Just your hand behind a thin piece of sand paper can leave grooves and low spots. It's also easier on your hands. For inside curves try wrapping the sand paper around a short section of garden or heater hose. This will help approximate the concave curve and help stay away from sanding through hard edges. On hard edges, like the top ridge of a fender or leading edge of a hood, you need to do this by hand. A sanding block will quickly dig right through the paint on a hard edge and take you down to bare metal. This means primer and more sanding.
