A computer lab is a space which provides computer services to a defined community. Computer labs are typically provided by libraries to the public, by academic institutions to students who attend the institution, or by other institutions to the public or to people affiliated with that institution. Users typically must follow a certain user policy to retain access to the computers. This generally consists of the user not engaging in illegal activities or attempting to circumvent any security or content-control software while using the computers. In public settings, computer lab users are often subject to time limits, in order to allow more people a chance to use the lab, whereas in other institutions, computer access typically requires valid personal login credentials, which may also allow the institution to track the user’s activities. Computers in computer labs are typically equipped with internet access, while scanners and printers may augment the lab setup. Computers in computer labs are typically arranged either in rows, so that every workstation has a similar view of one end of the room to facilitate lecturing or presentations, or in clusters, to facilitate small group work. take the place of dedicated computer labs, although computer labs still have a place in applications requiring special software or hardware not practically implementable in personal computers.
Primer paints may be oil- or water-based and are used to seal unpainted surfaces to prevent covering coats of paint soaking in.

Valspar Paint, for instance, also produces paint branded as Laura Ashley, Eddie Bauer, Waverly, and more. These separate lines, or collections, have their own color wheel displays and are usually available wherever the primary brand, Valspar in this case, are sold. Other examples are Disney Paints, currently produced by Behr, and Ralph Lauren and Martha Stewart, formerly produced by Sherwin Williams. By licensing these names, paint companies and retailers are taking advantage of the popularity of these well-known brands to attract you to these paints; that way they don't have to use obnoxious colors to bring your attention to their color wheel. If you look at the colors in these displays you will notice that they are generally missing those bright, saturated tones. Instead, most of the colors are more neutralized. Naturally, these colors are much more attractive to paint on a wall in your home. So how does a paint company accomplish this color hypnosis of potential customers? Well, it starts with the sample card. Have you ever noticed how the brightest, most saturated color sample cards are always the first row you see in a paint display? Well you guessed it... paint companies are playing with a loaded deck (of sample cards, that is)! Purple is the most contradicting color, to start at least because it consists of two antagonists: hot red and cold blue, ice and fire. It is the most mysterious color. It was the last color to emerge in art. Purple has a lot of other shades that are less rich and more lightened and muted: starting from light-lilac and going up to ashy gray-purple, which can give the interior a certain style and exquisiteness.
