Venus cloud color question

[kaygee]

<p>What colors are the clouds of Venus to a human flying through them (at an altitude of about 50 km, if that helps)?</p><p>Does enough visible light penetrate the&nbsp;upper atmosphere to make the clouds visible to someone flying, say, in&nbsp;a plane through them?</p><p>Thanks!</p>

<p>Thanks! I'll try him out. He looks like a good knowlegdeable resource.&nbsp;I'm actually reading "Venus" by Ben Bova and he describes them as grayish-yellow.</p><p>I'm writing a short story in which the protagonist meets aliens in the Venus atmosphere and am trying to avoid wriitng any scientific howlers.</p><p><BR/>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>You know, I think I asked the exact same question here about a year ago.

<p>One piece of data which has emerged from Venus Express is that the atmosphere is extraordinarily turbulent, so a ride through the clouds could be a pretty bumpy one.</p> <div class="Discussion_UserSignature"> <p>---------------------------------------------------------------</p><p>http://orionsarm.com  http://thestarlark.blogspot.com/</p> </div>
