Color Wheels are wrong? How color vision actually works by
Color theory is a little obsession of mine. You’re here for startup advice, but this week I’m taking an indulgence. Leave a comment if you want to see more or fewer of these little distractions. Why are artists special? Ask any artist to explain how color works, and they’ll launch into a treatise about how the Three Primary Colors: red, blue, and yellow form a color “wheel:” Why “wheel?” Continuing this process produces the infamous color wheel you probably learned in school; a pretty, symmetrical, satisfying device in which each hue melds seamlessly and linearly into the next: Unfortunately, none of this stands up to even minor scrutiny. For example, open up your desktop printer and you’ll see something quite different: Three colors of ink which, when combined, produce all others: cyan, magenta, and yellow. But wait! Also it’s not as simple as saying “any three colors can produce all the others” because that’s clearly not true (by experiment). TVs and computers are different yet again.

It includes a giant selection of thirty repeatable textures ranging from paper to fabric to subtle grunge and noise. Each one of them is fully tile-able and will work perfect for website background or pattern overlays in photoshop. The zip file includes each texture in both 1200px and 500px sizes as well as a Photoshop .PAT file for easy integration.

A Guide to Preparing Files for Print With this guide, we are going to examine ways to prepare files for print, covering applications in the Adobe Creative Suite. The examples used are for InDesign, but can apply to Photoshop and Illustrator. This is a basic guide aimed to help people just starting out in the print design business or are looking to learn more about preparing files better to send to press. Understand the Basics With most print jobs, you should have specifications to adhere to. CYMK vs RGB A lot of the colors you create in RGB mode are not achievable using standard four-color process printing. Some exceptions are tradeshow signs or large format prints, but the best way to know for sure is to check with the printer. Four over Four (or 4/4) If you’re printing a flyer, you might be printing 4/4, which essentially means you are printing four color on the front and four color on the back. For postcards, you might print 4/1: four color on the front and 1 spot color on the back. Print Layout Rich Black vs Black (100 K)

Light & The Eye • scotopic or dim light adapted rods (denoted by V' and containing the photopigment rhodopsin), most sensitive to "green" wavelengths at around 505 nm • short wavelength or S cones, containing cyanolabe and most sensitive to "blue violet" wavelengths at around 445 nm. • medium wavelength or M cones, containing chlorolabe and most sensitive to "green" wavelengths at around 540 nm • long wavelength or L cones, containing the photopigment erythrolabe and most sensitive to "greenish yellow" wavelengths at around 565 nm As the figure shows, there is a large number of differences between rhodopsin (taken as baseline) and the S photopigment, and a similarly large number of differences between the S and M photopigments. Photopigments do not catch light particles the way a bucket catches rain. Measuring Photoreceptor Light Sensitivity. Four kinds of spectra were obtained with four distinct absorptance peaks at 420, 495, 530 and 560 nm. Five Views of the Cone Fundamentals. 1. 2. 3. 4. 5.

Sortable Color Table | JavaScript Examples The table shown below represents the named colors that form part of CSS Color Module Level 3, derived from the SVG 1.0 specification. Each color is depicted in a row, with a 1) color swatch, 2) its standardized name, 3) its hue, saturation, and lightness (according to the HSL color space), 4) its representation as an HSL-formatted CSS style property value, 5) its red, green, and blue channel levels (according to the sRGB color space), and 6) its hex formatted RGB value. What makes the table most compelling is that it is sortable by any one of the colors' properties, so you can get a sense of how properties such as hue, saturation, lightness, red level, etc. relate to different colors by sorting on those properties - in either ascending or descending order. Indicators alongside the column values also provide cues for visual reference.

Color Theory For Game Design 1 of 4 – Fundamentals - Howtonotsuckatgamedesign.com This is a multipart article on color design for games. It is aimed at game designers and game artists alike and focusses on how to use color when crafting player experiences. Check the color theory readlist tag for all 4 parts of this series and the color design tag for all things games and color. Definitions are mostly custom made by me, since most color design literature is specialized for other creative fields – such as painting, print, screen design – and not suited for what we are going to talk about here. However, the following definitions have proven to be quite effective in the field. Okay, we dig into part 1 now. 1.Mickey Mouse model sheet ©Disney / 2. 2001 A Space Odyssey palette via / 3. artist’s oil color palette / 4. interior design concept via In non-interactive media, color palettes serve the purpose of creating images. We get even more overlap to games with fields like interior design, industrial design or fashion. Okay, here is what we do. Braid Team Fortress 2 1. 1. Limbo

Geometry of the Universe Can the Universe be finite in size? If so, what is ``outside'' the Universe? The answer to both these questions involves a discussion of the intrinsic geometry of the Universe. At this point it is important to remember the distinction between the curvature of space (negative, positive or flat) and the toplogy of the Universe (what is its shape = how is it connected). It is possible to different curvatures in different shapes. There are basically three possible shapes to the Universe; a flat Universe (Euclidean or zero curvature), a spherical or closed Universe (positive curvature) or a hyperbolic or open Universe (negative curvature). All three geometries are classes of what is called Riemannian geometry, based on three possible states for parallel lines The conformal space-time diagram is a good tool use for describing the meaning of CMB anisotropy observations.

Color Psychology by David Johnson Like death and taxes, there is no escaping color. It is ubiquitous. Yet what does it all mean? Why are people more relaxed in green rooms? Colors often have different meanings in various cultures. Black Black is the color of authority and power. White Brides wear white to symbolize innocence and purity.

Blue The color of the sky and the ocean, blue is one of the most popular colors. Green Currently the most popular decorating color, green symbolizes nature. Yellow Cheerful sunny yellow is an attention getter. Purple The color of royalty, purple connotes luxury, wealth, and sophistication. Brown Solid, reliable brown is the color of earth and is abundant in nature. Colors of the Flag In the U.S. flag, white stands for purity and innocence. Food for Thought While blue is one of the most popular colors it is one of the least appetizing.
