Color terms are easily learned, and they serve several cognitive functions, including efficient communication about color, as assessed by information theory, despite variations in lighting and individual differences in visual perception. Languages differ in having 2 to 16 basic color terms, but the lexical color categories they define are remarkably similar.</p><p style="box-sizing: border-box; margin: 0px 0px 10.5px; caret-color: rgb(50, 50, 50); color: rgb(50, 50, 50); font-family: "Open Sans", Helvetica, Arial, sans-serif; font-size: 14px;" class="">In this webinar hosted by the Color Technical Group, Delwin Lindsey and Angela Brown from Ohio State University will discuss these variations and regularities using information theory. They also will discuss how human perception and the need for social communication about color worked together to create color lexicons, and how these lexicons might influence human mental representations of color.</p><p style="box-sizing: border-box; margin: 0px 0px 10.5px; caret-color: rgb(50, 50, 50); color: rgb(50, 50, 50); font-family: "Open Sans", Helvetica, Arial, sans-serif; font-size: 14px;" class=""><span style="box-sizing: border-box; font-weight: 700;" class="">Subject Matter Level:</span><span class="gmail-Apple-converted-space"> </span>Intermediate - Assumes basic knowledge of the topic</p><p style="box-sizing: border-box; margin: 0px 0px 10.5px; caret-color: rgb(50, 50, 50); color: rgb(50, 50, 50); font-family: "Open Sans", Helvetica, Arial, sans-serif; font-size: 14px;" class=""><span style="box-sizing: border-box; font-weight: 700;" class="">What You Will Learn:</span></p><ul style="box-sizing: border-box; margin-top: 0px; margin-bottom: 10.5px; caret-color: rgb(50, 50, 50); color: rgb(50, 50, 50); font-family: "Open Sans", Helvetica, Arial, sans-serif; font-size: 14px;" class=""><li style="box-sizing: border-box;" class="">How human language compresses the 12-bit set of colors into a 1- to 3-bit chromatic color code</li><li style="box-sizing: border-box;" class="">How the language code for color varies, yet also shows remarkable similarities, across human languages</li><li style="box-sizing: border-box;" class="">How lexical color categories arise and how they are related to human color perception and societal need for color communication</li></ul><p style="box-sizing: border-box; margin: 0px 0px 10.5px; caret-color: rgb(50, 50, 50); color: rgb(50, 50, 50); font-family: "Open Sans", Helvetica, Arial, sans-serif; font-size: 14px;" class=""><span style="box-sizing: border-box; font-weight: 700;" class="">Who Should Attend:</span></p><ul style="box-sizing: border-box; margin-top: 0px; margin-bottom: 10.5px; caret-color: rgb(50, 50, 50); color: rgb(50, 50, 50); font-family: "Open Sans", Helvetica, Arial, sans-serif; font-size: 14px;" class=""><li style="box-sizing: border-box;" class="">Anyone who is interested in color vision</li><li style="box-sizing: border-box;" class="">Anyone who is interested in the efficient representation of color in computer displays to be viewed by multiple kinds of people (international viewers, color deficient viewers)</li></ul><h4 style="box-sizing: border-box; font-family: Lato, "Open Sans", sans-serif; font-weight: 400; line-height: 1.4; color: rgb(50, 50, 50); margin-top: 10.5px; margin-bottom: 10.5px; font-size: 18px; caret-color: rgb(50, 50, 50);" class=""><br style="box-sizing: border-box;" class="">About the Presenters:</h4><h4 style="box-sizing: border-box; font-family: Lato, "Open Sans", sans-serif; font-weight: 400; line-height: 1.4; color: rgb(50, 50, 50); margin-top: 10.5px; margin-bottom: 10.5px; font-size: 18px; caret-color: rgb(50, 50, 50);" class=""><img alt="" style="box-sizing: border-box; border: 0px; vertical-align: middle; max-width: 100%; float: left; margin: auto 10px;" apple-inline="yes" id="B421EE1E-8E2D-4DBD-AD43-9D2EED682777" src="cid:907286E6-C1CB-491F-B0DE-318A036FF3FC" class="">Angela M.

Brown is an experimental psychologist who studies the sensory development of the human visual system. After a Master's degree in Experimental Psychology (Rutgers University), she studied visual sensation and perception at the University of Michigan. She received her PhD in Experimental Psychology from the University of Michigan in 1981, with a dissertation on human color vision. Her primary area of research is visual development and includes work on visual acuity, contrast sensitivity and contrast discrimination, infant color vision, and infant vernier acuity. She collaborates with Delwin Lindsey in studies of the naming of colors by people around the world. So far, they have worked extensively on American English, Japanese, and Somali. They have also studied the naming and understanding of colors by the Hadza people of Tanzania, one of the last remaining hunter-gatherer societies in the world.<br style="box-sizing: border-box;" class=""><br style="box-sizing: border-box;" class=""> </p><h4 style="box-sizing: border-box; font-family: Lato, "Open Sans", sans-serif; font-weight: 400; line-height: 1.4; color: rgb(50, 50, 50); margin-top: 10.5px; margin-bottom: 10.5px; font-size: 18px; caret-color: rgb(50, 50, 50);" class=""><img alt="" style="box-sizing: border-box; border: 0px; vertical-align: middle; max-width: 100%; float: left; margin: auto 10px;" apple-inline="yes" id="C50B7375-7604-4546-BD53-1803530D796B" src="cid:D2A77631-80F9-43B9-9AD1-A174538DC1EF" class="">Delwin T.

He received an A.B. in physics from Pomona College and a Ph.D. in biopsychology from the University of Chicago. Dr. Lindsey’s research focuses on human vision, with particular emphasis on color vision. Dr. Lindsey's most recent research interests lie at the intersection of color perception and cognition: the factors that can explain individual and cross-cultural differences in color categorization. His research in this area combines a number of novel empirical and computational approaches to the study of human mental representations of color. Dr. Lindsey is a member of the Vision Sciences Society and the Optical Society. He is a past member of the editorial board of the Journal of the Optical Society of America A and continues to serve as guest editor on special issues of that journal.</p></div><div style="caret-color: rgb(34, 34, 34); color: rgb(34, 34, 34); font-family: Arial, Helvetica, sans-serif; background-color: rgb(255, 255, 255);" class=""><br class=""></div><div style="caret-color: rgb(34, 34, 34); color: rgb(34, 34, 34); font-family: Arial, Helvetica, sans-serif; background-color: rgb(255, 255, 255);" class="">Hope to see you there!</div><div style="caret-color: rgb(34, 34, 34); color: rgb(34, 34, 34); font-family: Arial, Helvetica, sans-serif; background-color: rgb(255, 255, 255);" class=""><br class=""></div><div style="caret-color: rgb(34, 34, 34); color: rgb(34, 34, 34); font-family: Arial, Helvetica, sans-serif; background-color: rgb(255, 255, 255);" class="">-Francisco</div><div style="caret-color: rgb(34, 34, 34); color: rgb(34, 34, 34); font-family: Arial, Helvetica, sans-serif; background-color: rgb(255, 255, 255);" class=""><span style="caret-color: rgb(33, 37, 41); color: rgb(33, 37, 41); font-family: Montserrat, sans-serif; font-size: 16.959999084472656px; font-weight: bold;" class=""><br class=""></span></div><div style="caret-color: rgb(34, 34, 34); color: rgb(34, 34, 34); font-family: Arial, Helvetica, sans-serif; background-color: rgb(255, 255, 255);" class=""><img data-surl="cid:ii_ktaifpp20" alt="17 Sept VC Webinar.jpg" apple-inline="yes" id="B6BF9AEA-C730-4385-9564-DB8DD9E2BA26" src="cid:4448396C-7193-4A98-BBC5-0F1CC6E6E111" class=""><br class=""></div><div style="caret-color: rgb(34, 34, 34); color: rgb(34, 34, 34); font-family: Arial, Helvetica, sans-serif; background-color: rgb(255, 255, 255);" class=""><br class=""></div></body></html>
