alamat palsu: colorblind

I came across this wonderfully imaginative and informative post about colorblindness, so I simply had to reproduce it (without stealing bandwidth, of course) for my readers who may have not seen it. My own grandfather was colorblind and his wife, my grandmother was an artist. I always wondered how he saw her paintings. Now I know. <a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgx3KzrNW4iG-lD77HSsCXO-5fa0_oJj8dcP26Gs7lU3kayBaiqESXkO_g6DFVfiCTPumjZyVsqcnNp-lB_NajFXvOlkW-rkclFPgm0wECgp2HfpEgvsCEa5B1jNHrBWiRs-0UT3Z12JizP/s1600-h/1566.pic.jpg" onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}"><img alt="" border="0" id="BLOGGER_PHOTO_ID_5227830104201435954" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgx3KzrNW4iG-lD77HSsCXO-5fa0_oJj8dcP26Gs7lU3kayBaiqESXkO_g6DFVfiCTPumjZyVsqcnNp-lB_NajFXvOlkW-rkclFPgm0wECgp2HfpEgvsCEa5B1jNHrBWiRs-0UT3Z12JizP/s400/1566.pic.jpg" style="cursor: pointer;" /></a> In the U.S. 7% of the male population – or about 10.5 million men – and 0.4% of the female population either cannot distinguish red from green, or see red and green differently. Color blindness affects a significant amount of the population, and it is even more prevalent in more isolated populations with a smaller gene pools. It is mostly a genetic condition, though it can be caused by eye, nerve, or brain damage, or due to exposure to certain chemicals. For those of us who see colors just fine, it is hard to imagine what those with color blindness are seeing. Luckily humans are smart and have created technology like the <a href="http://colorfilter.wickline.org/">Color Blind Web Page Filter</a>. Popular Websites: As Seen by the Color Blind The <a href="http://colorfilter.wickline.org/">Color Blind Web Page Filter</a>, which was used in this post to demonstrate the different types of colorblindness, allows you to view what a site looks like to people with each type of color blindness.

Normally, there are three kinds of cones, each containing a different pigment. The cones are activated when the pigments absorb light. The absorption spectra of the cones differ; one is maximally sensitive to short wavelengths, one to medium wavelengths, and the third to long wavelengths (their peak sensitivities are in the blue, yellowish-green, and yellow regions of the spectrum, respectively). The absorption spectra of all three systems cover much of the visible spectrum, so it is not entirely accurate to refer to them as “blue”, “green” and “red” receptors, especially because the “red” receptor actually has its peak sensitivity in the yellow. The sensitivity of normal color vision actually depends on the overlap between the absorption spectra of the three systems: different colors are recognized when the different types of cone are stimulated to different extents. Red light, for example, stimulates the long wavelength cones much more than either of the others, and reducing wavelength causes the other two cone systems to be increasingly stimulated, causing a gradual change in hue. Many of the genes involved in color vision are on the X chromosome, making color blindness more common in males than in females. Types of Color Blindness There are three types of inherited or congenital color vision deficiencies: monochromacy, dichromacy, and anomalous trichromacy. Monochromacy <a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgTECIYW8pad84pUJe6zTAhk9r1m1UV-5pwKucarX8IjdvpacEbc3A65N1JNma-EFJ2K1LfHpyi8x3fEI35HqE96UzVNnr7Y8LEGshy9BK_B3G4apRKT12fFCoqawC9b1jaqqMncbn43q0k/s1600-h/a-mono.jpg" onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}"><img alt="" border="0" id="BLOGGER_PHOTO_ID_5227834796663208354" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgTECIYW8pad84pUJe6zTAhk9r1m1UV-5pwKucarX8IjdvpacEbc3A65N1JNma-EFJ2K1LfHpyi8x3fEI35HqE96UzVNnr7Y8LEGshy9BK_B3G4apRKT12fFCoqawC9b1jaqqMncbn43q0k/s400/a-mono.jpg" style="cursor: pointer;" /></a> Monochromacy, also known as “total color blindness”, is the lack of ability to distinguish colors; caused by cone defect or absence. Monochromacy occurs when two or all three of the cone pigments are missing and color and lightness vision is reduced to one dimension. Dichromacy Dichromacy is a moderately severe color vision defect in which one of the three basic color mechanisms is absent or not functioning. It is hereditary and sex-linked, affecting predominantly males. Dichromacy occurs when one of the cone pigments is missing and color is reduced to two dimensions. <a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiBW0fgP2NYR2eGDpABS4Se2ZI97Hn7TdtSotg5Jb1Ze0Aw2y5vuIc2sRnkgdTCA7O7wU-6V79Uwjl_5tZPpEZodCRy6DhpygH8zdafX778_EEZc-NKvIM8zvw4d7OX1Rn42dEwpYlGHYv3/s1600-h/protan.jpg" onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}"><img alt="" border="0" id="BLOGGER_PHOTO_ID_5227834454805629826" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiBW0fgP2NYR2eGDpABS4Se2ZI97Hn7TdtSotg5Jb1Ze0Aw2y5vuIc2sRnkgdTCA7O7wU-6V79Uwjl_5tZPpEZodCRy6DhpygH8zdafX778_EEZc-NKvIM8zvw4d7OX1Rn42dEwpYlGHYv3/s400/protan.jpg" style="cursor: pointer;" /></a> Protanopia is a severe type of color vision deficiency caused by the complete absence of red retinal photoreceptors.
