The Realities And Myths Of Contrast And Color

The Realities And Myths Of Contrast And Color

26 min readAccessibility, Design, UsabilityIn this article, Andrew Somers, a 35-year veteran of the Hollywood film and television industry, shares his experience about the hard-fought battles and lessons learned designing for illuminated presentations.A long, long time ago, in a land far, far away…By “long ago,” I mean circa 1924, and by “far away,” I mean London, UK., scientists W. D. Wright and J. Guild conducted color-matching experiments measuring the boundaries of human color vision. Their work was combined by the International Commission on Illumination (the CIE) into the 1931 CIE “standard observer “, a sort of “mathematical eyeball” that models how we see color. And with that, modern colorimetry was born.(Large preview)Colorimetry is the basic science that made color television possible, and of course, our modern displays and smartphones — all our modern electronic color technology traces back to the 1931 CIE color space.This colorful, kidney-shaped graphic represents the limits of human color vision — the smaller triangle inside marks the colors that can be displayed on a standard sRGB monitor, and the larger triangle represents P3 displays.(Large preview)Each corner of the triangle is one of the three “primaries” of light: red, green, and blue. The area inside the triangle represents how those three colors appear when added together in various combinations, hence the term “additive color model.”The use of the term “primary” is a bit of a misnomer, though, as there is no set of three real colors in the real world that can be mixed to create all the other colors. Only a subset of colors, as defined by these triangles.In The Eye Of The Beholder Or The Mind?A Simple Overview Of Human VisionLight is focused by the eye’s lens onto the light-sensitive cells in the back of the eye, known as the retina. The cells we are most interested in are called cones, which are responsible for our daylight and color vision. A different kind of cells, called rods, gives us night vision, but rods are not particularly helpful for tasks like reading, and rods essentially shut down in daylight conditions.(Large preview)Standard or “normal” vision uses three cone types. They are sometimes but inaccurately called “red,” “green,” and “blue” cones, but there is much more to this story.Color Is Not RealIs color not real? That’s a provocative statement for an article on color and contrast. But the reality is that “color” and “contrast” are not strictly real in an absolute sense. “Colored” light is simply light of different wavelengths or frequencies, like different notes on a piano. In fact, the scientific names for the cone cells in our eye are L, M, and S cones which stand for the long, medium, and short wavelengths of light they are most sensitive to.(Large preview)The L cone actually has a peak sensitivity near yellow/green. But the fact its response curve extends into deep reds gives a differential from the M cone that allows humans to perceive “red” as a unique hue.  » Read More

Is the Dynamic Island plain stupid or the next revolutionary UX pattern?


Let's talk about Web Design

The term "web design" describes the layout of websites that are seen online. Instead of software development, it typically refers to the user experience components of website development. The primary focus of web design used to be creating websites for desktop browsers, but from the middle of the 2010s, designing for mobile and tablet browsers has gained significance.

What is a webdesigner?

A web designer is responsible for a website's look, feel, and occasionally even content. For instance, appearance refers to the colors, text, and images utilized. Information's organization and categorization are referred to as its layout. An effective web design is user-friendly, aesthetically pleasing, and appropriate for the target audience and brand of the website. Many websites focus on keeping things simple so that viewers won't be distracted or confused by additional information and functionality. Removing as many potential sources of user annoyance as possible is a crucial factor to take into account because the foundation of a web designer's output is a site that gains and nurtures the trust of the target audience.

Responsive and adaptive design are two of the most popular techniques for creating websites that function well on both desktop and mobile devices. In adaptive design, the website content is fixed in layout sizes that correspond to typical screen sizes, while in responsive design, information moves dynamically based on screen size. A layout that is as consistent as possible across devices is essential to preserving user engagement and trust. Designers must be cautious when giving up control of how their work will appear because responsive design can be challenging in this area. While they might need to diversify their skill set if they are also in charge of the content, they will benefit from having complete control over the final output.

What does a web design worker do?

A web designer is a member of the IT industry who is in charge of planning a website's structure, aesthetic appeal, and usability.

A skilled site designer must possess both technical know-how and creative graphic design abilities. They must be able to envision how a website will seem (its graphical design) and how it will operate (conversion of a design into a working website).

The terms web developer and designer are frequently used interchangeably but erroneously. In order to construct more complex interactions on a website, such as the integration with a database system, a web developer is frequently more likely to be a software developer who works with programming languages.
