The emperor penguin (Aptenodytes forsteri) is the tallest and heaviest of all living penguin species and is endemic to Antarctica. The male and female are similar in plumage and size, reaching 122 cm (48 in) in length and weighing from 22 to 45 kg (49 to 99 lb). Feathers of the head and back are black and sharply delineated from the white belly, pale-yellow breast and bright-yellow ear patches. Like all penguins it is flightless, with a streamlined body, and wings stiffened and flattened into flippers for a marine habitat. Its diet consists primarily of fish, but also includes crustaceans, such as krill, and cephalopods, such as squid. While hunting, the species can remain submerged around 20 minutes, diving to a depth of 535 m (1,755 ft). It has several adaptations to facilitate this, including an unusually structured haemoglobin to allow it to function at low oxygen levels, solid bones to reduce barotrauma, and the ability to reduce its metabolism and shut down non-essential organ functions.
Flat or Dead-Flat Oil - Provides a completely flat, oil-based finish. Generally used on walls but not suitable for areas of high wear. If you are grappling with the problem of choosing a woodwork colour to go with neutral walls, check out Architectural Colours by David Oliver, the founder of Paint & Paper Library. He arranged his off-whites for ceilings, cornices, walls and woodwork in chromatical groups and the concept has been so well received that chromatically arranged colours, such as soft greys, greens and pinks, have been introduced. Limewash - Made from slaked lime and water, this paint is good for porous surfaces such as brickwork, render and plaster and gives a chalky finish. It is available from specialist companies.
You're not looking for perfection here, but you do want to eliminate every shiny spot of paint. When properly scuffed the paint should have a smooth, but dull matte finish. The reality is that the guys shooting paint, even at the cheapest shops, know how to do it. They spray a dozen cars a week and have plenty of practice laying down smooth, consistent coats of paint. They work quickly and efficiently because they have to or they don't make money. They don't really make their money on shooting paint. They profit from body work because it takes time and insurance work because it pays well. However, if you put a coat of pure white primer (which has a score of 0) on top of the brown color wall first, this immediately brings your luminosity score down to 4 (8 + 0 = 8/2 = 4, the average). This means you may only need one coat of yellow paint to give you the right hue and saturation. In reality of course, you will always want to do at least 2 coats. But even with a total of 3 coats (primer and paint) you are way ahead of the paint-only option. Cutting Down on Paint Chemicals. Everyone knows the nasty smell of paint drying - worse with oil-based paints, but also noticeable with vinyl emulsions. This is caused by paint solvents containing VOCs. They are proven health risks, and can cause allergies, headaches and breathing problems and irritate eyes, nose and throat. They are also an environmental hazard.
