Making Cash On The Web is a serious attempt to compile useful information about making money on the internet. It is a combination of things that I have learned myself, as well as information culled from other sources. It is NOT about get rich quick schemes, or wierd marketing programs.

Somewhere between 8% and 12% of males (and about 1/2 a percent of females) are colorblind. The most common form of this involves a difficulty distinguishing between reds and greens.
As a webmaster, you can’t afford to lose ten percent of your potential customers because they can’t make out what’s on the screen.
The most obvious thing is to make sure that you don’t have red text on a green background, or vice versa.
But there may be other parts of your site that you haven’t thought about. To find out whether your site is “color blind friendly”, go to Vischeck and run a test. It allows you to check for the three most common forms of color blindness.
If it turns out that you site has issues—especially with the text, you might consider changing some colors.
