Pixel Spreadsheet Microscope image of an iPhone screen.It really is just a spreadsheet. Digital photographs are actually just spreadsheets. When you take a photo, your camera measures the amount of red, green and blue light hitting each pixel, ranks them on a scale from 0 to 255 and then records those values as a spreadsheet. Matt Parker found a way to actually open digital photos as spreadsheets in Excel. The Fascinating Neuroscience Of Color Neuroscientist Bevil Conway thinks about color for a living. An artist since youth, Conway now spends much of his time studying vision and perception at Wellesley College and Harvard Medical School. His science remains strongly linked to art--in 2004 he and Margaret Livingstone famously reported that Rembrandt may have suffered from flawed vision--and in recent years Conway has focused his research almost entirely on the neural machinery behind color. "I think it's a very powerful system," he tells Co.Design, "and it's completely underexploited." Conway's research into the brain's color systems has clear value for designers and artists like himself. It stands to reason, after all, that someone who understands how the brain processes color will be able to present it to others in a more effective way.

Color Theory For Designers, Part 2: Understanding Concepts And Terminology Advertisement If you’re going to use color effectively in your designs, you’ll need to know some color concepts and color theory terminology. A thorough working knowledge of concepts like chroma, value and saturation is key to creating your own awesome color schemes. In Part 1: The Meaning of Color1 of our color theory series, we covered the meanings of different colors. Here, we’ll go over the basics of what affects a given color, such as adding gray, white or black to the pure hue, and its effect on a design, with examples of course.
Color Theory for Designers, Part 1: The Meaning of Color Color in design is very subjective. What evokes one reaction in one person may evoke a very different reaction in somone else. Sometimes this is due to personal preference, and other times due to cultural background. Color theory is a science in itself. Studying how colors affect different people, either individually or as a group, is something some people build their careers on. And there’s a lot to it.

To see the updates, check out my latest post here Test gratuit d'acuité visuelle How color vision works Human can distinguish colors when incoming light reacts with the cone cells in the retina of eye. There are three types of cone cells. Based on how they respond to light of wavelengths you will perceive the three basic colors; red, green and blue.
