Colour Contrast Check –

The Colour Contrast Check Tool allows to specify a foreground and a background colour and determine if they provide enough of a contrast “when viewed by someone having color deficits or when viewed on a black and white screen”[W3C].

The tool will indicate that the colours pass the test if both the colour difference and the brightness difference exceed their threshold. It will indicate that it sort of passes if only one of the two values exceed their threshold. And finally, it’ll fail to pass if neither value exceeds its threshold.

You can enter a three character value (eg: 036) and it’ll automatically convert it to it’s six character version.

A CAPTCHA Solution For Classic ASP

These days spam is an increasing problem for everybody, including blogs and comment boards. If your page has a form your visitors can submit, it could well be a target for a spammer. This is actually quite easy to do. You write a piece of software, often called a robot or spider, and program it to crawl the Internet looking for forms. The spider automatically enters data in the form fields and submits the form. It doesn’t need to click the button like you and me. The spam could be Viagra or porn, but also innocent looking links to some web page. The spider does this in order to improve their ranking in the search engines. The more links they spam out, the better ranking they get.
