@unpublished{Gunther2007_0,<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Abstract = {In this talk I will be discussing one study from my dissertation and one from my post-doctoral fellowship, followed by a miniature version of a lecture from the Interdisciplinary Color Course I have taught and would love to teach again someday. The first study looks at how the ratio of red to green cones (which vision scientists call L and M, for long-wavelength-sensitive and medium-wavelength-sensitive) in the retina affects perception. Amongst people with normal color vision, there is surprising variability in cone ratio, ranging from close to 1:1 to nearly 20:1 L:M cones. Do these differences affect our perceptions? And what does this say about neural wiring? For the second study, I will discuss two novel genetic mutations that we have identified that appear to be disrupting the S-cone (short-wavelength-sensitive, or “blue” cone) vision of these subjects, leading to a form of colorblindness known as tritanopia. I will also present our hypothesis, and supporting data, that tritanopia is degenerative. Then I will shift gears and present the Mauve Story from my Interdisciplinary Color Course – mauve was the first synthetic dye, and its discovery revolutionized not only the dye industry, but all of chemistry, especially organic chemistry.},<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Author = {Karen Gunther},<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Keywords = {color},<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Month = {April},<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Note = {In seminar 'Chester F.
