<h3>Good Contrast</h3>
<p>Color contrast between the background and the foreground content should be sufficient enough to ensure readability. Example below displays two cases with good and bad samples.</p>
<div class="flex">
<div class="h-8rem w-8rem flex justify-content-center align-items-center mr-5 font-bold bg-blue-600" style="borderradius: 10px">

<span class="text-white">BAD</span>
</div>
</div>
<h3>Vibration</h3>
<p>Color vibration is leads to an illusion of motion due to choosing colors that have low visibility against each other. Color combinations need to be picked with caution to avoid vibration.</p>
<div class="flex">

<span class="text-blue-500">VIBRATE</span>
</div>
</div>
<h3>Dark Mode</h3>
<p>Highly saturated colors should be avoided when used within a dark design scheme as they cause eye strain. Instead desaturated colors should be preferred.</p>

<h3>Visual Impairments</h3>
<p>
Blindness, low-level vision or color blindness are the common types of visual impairments. Screen magnifiers and the color blind mode are usually built-in features of the browsers whereas for people who rely on screen readers, page
developers are required to make sure content is readable by the readers. Popular readers are
<a href="https://www.nvaccess.org" alt="NVDA Reader"> NVDA </a>
,
<a href="https://www.freedomscientific.com/Products/software/JAWS/" alt="JAWS Reader"> JAWS </a> and
<a href="https://www.chromevox.com" alt="ChromeVox Reader"> ChromeVox </a>
.
</p>
<h3>Hearing Impairments</h3>
<p>
Deafness or hearing loss refers to the inability to hear sounds totally or partially. People with hearing impairments use assistive devices however it may not be enough when interacting with a web page. Common implementation is providing
textual alternatives, transcripts and captions for content with audio.
</p>
<h3>Mobility Impairments</h3>
<p>
People with mobility impairments have disabilities related to movement due to loss of a limb, paralysis or other varying reasons. Assistive technologies like a head pointer is a device to interact with a screen whereas keyboard or a
trackpad remain as solutions for people who are not able to utilize a mouse.
</p>
<h3>Cognitive Impairments</h3>
<p>
Cognitive impairments have a wider range that includes people with learning disabilities, depression and dyslexia. A well designed content also leads to better user experience for people without disabilities so designing for cognitive
impairments result in better design for any user.
