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.
Rajput paintings depict a number of themes, events of epics like the Ramayana and the Mahabharata, Krishna's life, beautiful landscapes, and humans. Miniatures were the preferred medium of Rajput painting, but several manuscripts also contain Rajput paintings, and paintings were even done on the walls of palaces, inner chambers of the forts, havelies, particularly, the havelis of Shekhawat.The colors extracted from certain minerals, plant sources, conch shells, and were even derived by processing precious stones, gold and silver were used. The preparation of desired colors was a lengthy process, sometimes taking weeks. Brushes used were very fine.
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.
The salt and alum should be dis-solved in 4 gallons of hot water, after which the molasses may be added to the mixture. The resulting clear solution is then added to the lime paste, stirred vigorously, and thinned with water to the desired consistency. This whitewash has a yellow tinge when first applied, but the color disappears in a few days leaving a white film.
Following a European directive, the British paint industry has reduced VOCs in two stages, the second of which came into force in January last year.
Today, it is increasingly easy to source ecologically sound paints, as most specialist ranges, such as Ecos, Earthborn, Georgina Barrow and Auro are available via mail order. There is a wealth of colour options in these pre-mixed ranges that include lush shades and muted palettes, reflecting their natural ingredients. Ecos continues to lead the field. It has recently developed Atmosphere Purifying Paint, which absorbs and neutralises volatile chemicals, solvents and VOCs from the atmosphere in a home.
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.
