Actual for You - Web Design: Accommodating Color-Blind Browsers
Google has announced the addition of some truly useful features to make Google Sitemaps an even better tool for the web. They’ve given their site a facelift and made it easier to navigate. They asked for feedback and they listened. Hopefully, the result is something everyone will love.A feature that many webmasters will be happy to know about is the notification of violations. No longer will they be left in the dark about what is happening. They will know if they have violated the webmaster guidelines and why.The rules are pretty simple. Create your site that is truly helpful to your users and avoid doing naughty things just to increase your ranking. Linking to bad si
• Navigational text which includes image and button text, menus, headers, and sub-headers need to be clear. Make sure that these items are very high in contrast. This means that you should either make these items black and white or opposite ends of the color saturation pole.
• When using large format pieces of copy, using dark text on a white background is absolutely essential. Use as much color as you want in the surrounding parts of the page, as long as it doesn't take away from the contrast of the text.
• If you aren't sure if a page is contrasted enough, desaturate your website in Fireworks or Adobe Photoshop and see if the images still have an impact. Desaturating the image will remove all the color from the image and this way you will be able to tell if the image has enough contrast without color to be seen.

"Without the chance to meaningfully participate in steering one’s own destiny, without the opportunity to gain the sincere respect of one’s own peers, without an honest stake in making the community more successful through one’s own work and ideas, employability can quickly decay into generic training programs or bogus choices..." --"Beyond Empowerment: Building a Company of Citizens" by Brook Manville, Josiah Ober, page 52, Harvard Business Review January 2003.Today, businesses are dealing with massive change issues spearheaded by new strategic initiatives around technology. So much is possible! We can demographically get into our customer’s heads, craft alliances that acc
Approximately 8% of males and 0.5% of females have a deficit in their color vision, due to an inherited abnormality in the cone cells of the retina. It’s unwise not to take these browsers into account as their special needs could mean that 1 out of 20 visitors might not be able to use a website at all or with great difficulty. This greatly depends on whether the website in question is “Color-blind friendly”. Text might be illegible and images unrecognizable. Consider the amount of visitors and customer conversions that you might lose if your website is not accessible and usable by the colorblind.
It is seen is considered professional, and stands your company in good stead to establish a website that doesn't exclude the impaired or disabled. After all, an accessible website is more likely to be ranked well with the search engines than an inaccessible website.
There are three different color vision impairments to take into consideration.
Color is essentially perceived because a light particle, or photon, triggers a cell in the eye which is called a cone. The cone sends a signal to the brain that it has received a trigger. Each kind of cone is responsible for sensing a range of wavelength thus centering on red, green, or blue. Combinations of these cones fire at different intensities to produce the spectrum of colors in various degrees of brightness and saturation. Sometimes the instructions for the cones are "wired" abnormally, causing the cones to react to a different range of light. Ninety-nine percent of color-blind people have trouble distinguishing between red and green.
• Trichromat Vision:"normal" color vision, uses red/green/blue color receptors ... this is the kind of vision that 11 out of 12 visitors have.
• Anomalous Trichromat Vision: Anomalous Trichromat vision, uses three color receptors but one pigment is misaligned
• Protanomaly Vision: reduced color red sensitivity
• Deuteranomaly Vision (common): reduced color green sensitivity
• Tritanomaly Vision: reduced color blue sensitivity
• Dichromat Vision: Dichromat vision, uses only 2 of the 3 visual pigments - red, green or blue is missing.
• Protanopia Vision: unable to view color red.
• Deuteranopia Vision: unable to view color green.
• Tritanopia Vision: unable to view color blue.
• Monochromat Vision: (able to see only one color)
This unpredictability makes it hard to simulate the color blind browser. However, there are ways and means to ‘get around’ these limitations.
Designing for color-blind browsers
Although designing a website for the colorblind will not limit your color palette, you’ll need to be wary of the color combinations that you use. Learning what color combinations not effective is a great place to start.
As a rule of thumb, do away with Red and Green Combinations. Although most people see Red and Green as contrasting, those with Anomalous Trichromat Vision Colorblindness will not be able to tell these colors apart. This also goes for combinations with variations of green and red, including colors such as purple and orange.

The accounting records of many smaller non-profit organisations such as clubs, cultural societies and small undertakings are often kept by means of a single entry accounting system. Nevertheless, details of the financial activities of such organisations and undertakings are available in different documents such as bank statements, invoices, accounts, wage sheets and minute books.There are two major disadvantages to such incomplete (non-double entry basis) accounting records: (1) a great deal of useful information may be lost. It is possible to prepare financial accounting statements from the available information, but this may be more difficult than when complete records a

Do you have an idea for a product or service? Would you like to start a business? If so you will want to read this article. Here’s the good news: Every product or service ever invented by mankind started as an idea. An intangible thought impulse that was turned into reality through the efforts of one or more people working together in an intelligent and harmonious manner. Behind those successful ideas were organized written plans—business plans that laid the foundation and illustrated the path to success for the business owner and investors who funded the project. Then, those plans coupled with the burning desire of the entrepreneur to see the project through to completion is wh

Just imagine the horror of being named by a celebrity. You could be stuck being known as “Kal-El,” “Shiloh,” “Apple,” or even “Suri” for the rest of your life.Unfortunately, people underestimate the impact a name has on first impressions. A name is more than just a word; it is a representation of who you are. If any of these celebrity kids eventually enter the business world, they may discover the dangers of a bad name.In business, your email address can be as influential in representing you as your birth name is in your everyday life. The email address you choose could affect how clearly communicated it is over the phone, how well it is remembered, and how quickl

If you are already a sales person, or if you are hoping to gain a sales position, then you should consider your resume to be the first step in a sales presentation that sells you as an employee to your prospective employer. Even if you consider yourself to be somewhat of an expert in sales, you might find that selling yourself using one or two sheets of paper is much more daunting than selling items on a sales floor. This is where a sample sales resume can be an invaluable tool.With a sample sales resume, you’ll learn that your ability for selling must become notably more fine-tuned so that you can compete among many other sales-oriented people. It will help you to create

• When a dichromatic person sees something green, both the red and green cones are activated. Since red and green make yellow, green objects appear yellow. A site that contains green text on a yellow background causes both the text and the background to appear yellow, making the text invisible. A dichromatic person with green cones shifted toward the red will also see the green as more yellow.
• Use Vischeck online which also allows you to see what a design would look like to someone who is color blind. Either run Vischeck on your own image files or on a web page. The Web Design Evaluation Tool is also a free online utility that allows you to see the 3 different ways that your page can look depending on the viewer's vision and color disability.
Color-blind browsers form a huge part of the global community and therefore should be taken into consideration when designing a website.
