But this post prompted me to try to answer a nagging question that I've never found the answer to: why does violet *look* purple? As in, when people try to match a spectral color with a mix of red/green/blue, why does violet get a mix of red and blue, as shown in <a href="https://en.wikipedia.org/wiki/CIE_1931_color_space#/media/File:CIE_1931_XYZ_Color_Matching_Functions.svg" rel="nofollow">this</a> image?<br />My first guess was that red cones have a second region of sensitivity in the blue/violet range, but <a href="https://en.wikipedia.org/wiki/Color_vision#/media/File:Cone-fundamentals-with-srgb-spectrum.svg" rel="nofollow">wikipedia</a> doesn't seem to think that's the case.<br /><br />Anyway, I landed on the wikipedia page about <a href="https://en.wikipedia.org/wiki/Rainbow#Supernumerary_rainbows" rel="nofollow">rainbows</a>, which points out that rainbows in the sky often *do* include purple, due to complicated interference things. <a href="http://www.smithsonianmag.com/smart-news/rainbows-dont-include-purple-light-so-why-do-they-sometimes-seem-180953190/" rel="nofollow">Here</a> is another link. So that makes me feel better about my rainbow song. (-:<br /><br />Also, color vision is weird. One of the violet/purple discussions I came across had a link to this <a href="https://www.moillusions.com/black-and-white-spanish-castle-in/" rel="nofollow">illusion</a>.Anonymoushttps://www.blogger.com/profile/00724754741498945720noreply@blogger.comtag:blogger.com,1999:blog-8946730821757640263.post-14691389342393658522017-02-20T08:46:17.987-08:002017-02-20T08:46:17.987-08:00The tune is also "Twinkle, Twinkle, Little St...The tune is also "Twinkle, Twinkle, Little Star."
