A few minutes later it shows the color spaces for people with various types of colourblindness.&lt;p&gt;Perhaps one could project one perceptual space into the other in a way that more-or-less preserves the original information, but essentially with more banding?&lt;p&gt;[0] &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.youtube.com&amp;#x2F;watch?v=xAoljeRJ3lU&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.youtube.com&amp;#x2F;watch?v=xAoljeRJ3lU&lt;/a&gt;</text><parent_chain><item><author>mrguyorama</author><text>The problem with colorblindness is a common one.
