There are people who are blind to certain colors. Human color blindness is hard to explain. In a single eye, there are millions of very small things called “cones.” They help us to see in bright light and to tell the difference between colors. There are also millions of “rods,” bu...
Is it a single color or many colors mixed together? Does it have a frequency like sound? And what are some of the common properties of light, such as absorption, reflection, refraction and diffraction? You might think scientists know all the answers, but light continues to surprise them. ...
Color contrast Using highly contrasting colors ensures text is distinguishable from its background. This allows people with color blindness and other vision impairments to be able to read and comprehend content. Navigation An online document should feature clear and consistent navigation.

Focus on usability to keep visitors on the page and provide a positive user experience. Ex...
Color blindness is not as strictly categorical as the various diagnoses make it out to be; people can have widely-varying degrees of color vision deficiencies in one or more categories. The tools I used to create these images are making educated approximations, but they’re still approximations....
However, if you find yourself in a situation where the potential employers ask disability-related questions that are illegal, do not confront them angrily. Instead, maintain your cool and calmly explain that you're not comfortable answering the question. You can ask them about the underlying ...

Science cannot ultimately explain why some people have near-death experiences. That's not to say that current scientific explanations are incorrect, but NDEs are complex, subjective and emotionally charged. Further, testing presents major challenges. Scientists can't purposely take someone to the ...
