On the Colors of Visual Pigment Chromophores
Dear Sir: All known visual pigments are formed by the combination of 1 I -cis retinal (Fig. 1) with a member of the family of proteins called opsins, found in the visual cells of vertebrates and invertebrates. The absorption maximum (X,,) of solutions of llCis retinal in aqueous detergents lies at about 385 mp. The absorption maxima of the visual pigments it gives rise to cover a range of at le...
متن کاملEubacteria show their true colors: genetics of carotenoid pigment biosynthesis from microbes to plants.
The opportunities to understand eubacterial carotenoid biosynthesis and apply the lessons learned in this field to eukaryotes have improved dramatically in the last several years. On the other hand, many questions remain. Although the pigments illustrated in Fig. 2 represent only a small fraction of the carotenoids found in nature, the characterization of eubacterial genes required for their bi...
متن کاملMapping colors from paintings to tapestries: rejuvenating the faded colors in tapestries based on colors in reference paintings
We addressed the problem of recovering or “rejuvenating” colors in a faded tapestry (the target image) by automatically mapping colors from digital images of the reference painting or cartoon (the source image). We divided the overall computational challenge into several subproblems, and implemented their solutions in Matlab: 1) quantizing the colors in both the tapestry and the referent painti...
متن کاملLuminance contours can gate afterimage colors and "real" colors.
It has long been known that colored images may elicit afterimages in complementary colors. We have already shown (Van Lier, Vergeer, & Anstis, 2009) that one and the same adapting image may result in different afterimage colors, depending on the test contours presented after the colored image. The color of the afterimage depends on two adapting colors, those both inside and outside the test. He...

With her sexual configurations theory (SCT), vanAnders (2015) wants to solve a number of problems with the current conceptualization of sexual orientation as defined by the sex of the partner(s) one is attracted toandhabitually indicatedwith theKinsey score varying from completely heterosexual to completely homosexual.
