Electromagnetic waves are often distinguished from mechanical waves. . Analyze how color can be used to create moods and illusions. Explain how primary colors are used to produce other colors on the color wheel. Describe the effects of intensity and value on various hues. 1Many different types of light microscopesare available each with their own strengths and limitationsA main tenant of good microscopy is to select the right tool microscope for the job at handPlease c Eric King. Humans perceive color when light enters the eye and is detected by the photoreceptors, called cones, which are mainly located in the fovea. We have trichromatic color vision which means we have three different kinds of cones that detect a specific wavelength of light, namely short (blue), medium (green), and long (red). How we perceive color also depends on how dim or bright the light is. .

Learn how to mix colors when painting. We encounter color everyday, everywhere, from billboards and posters to neon signs and social media posts. The ancient world was no different, as is evident from the traces of polychromy, or multiple colors, found covering the surfaces of ancient architecture and sculpture. Bright, eye-catching, and often bordering on what we would consider garish today, ancient civilizations colored their world by applying pigments and dyes to finished stone surfaces..
