The Expanding Gamut of Color on the Web

CSS was introduced to the web all the way back in 1996. At the time, most computer monitors were pretty terrible. The colors of CSS — whether defined with the RGB, HSL, or hexadecimal format — catered to the monitors of the time, all within the sRGB colorspace.

Most newer devices have a wide-gamut display. A gamut is the range of colors that can be displayed. A wide-gamut display is capable of showing more colors than sRGB. They use the … Read article “The Expanding Gamut of Color on the Web”

No-Comma Color Functions in CSS

There have been a couple of viral tweets about this lately, one from Adam Argyle and one from Mathias Bynes. This is a nice change that makes CSS a bit more clear. Before, every single color function actually needs two functions, one for transparency and one without, this eliminates that need and brings the syntax more-inline with CSS grammar overall.

Lemme remake the code blocks from Mathias’ tweet here:… Read article “No-Comma Color Functions in CSS”

Creating Color Themes With Custom Properties, HSL, and a Little calc()

Before the advent of CSS custom properties (we might call them “variables” in this article as that’s the spirit of them), implementing multiple color schemes on the same website usually meant writing separate stylesheets. Definitely not the most maintainable thing in the world. Nowadays, though, we can define variables in a single stylesheet and let CSS do the magic.

Even if you aren’t offering something like user-generated or user-chosen color themes, you might still use the concept of theming on … Read article “Creating Color Themes With Custom Properties, HSL, and a Little calc()”

The Best Color Functions in CSS?

I’ve said before that HSL is the best color format we have. Most of us aren’t like David DeSandro, who can read hex codes. HSL(a) is Hue, Saturation, Lightness, and alpha, if we need it.

hsl(120, 100%, 40%)

Hue isn’t intuitive, but it’s not that weird. You take a trip around the color wheel from 0 to 360. Saturation is more obvious where 0% has all the color sucked out, like grayscale, and 100% is fully rich color at … Read article “The Best Color Functions in CSS?”

A Handy Sass-Powered Tool for Making Balanced Color Palettes

For those who may not come from a design background, selecting a color palette is often based on personal preferences. Choosing colors might be done with an online color tool, sampling from an image, “borrowing” from favorite brands, or just sort of randomly picking from a color wheel until a palette “just feels right.”

Our goal is to better understand what makes a palette “feel right” by exploring key color attributes with Sass color functions. By the end, you will … Read article “A Handy Sass-Powered Tool for Making Balanced Color Palettes”

Converting Color Spaces in JavaScript

A challenge I faced in building an image “emojifier” was that I needed to change the color spaces of values obtained using getImageData() from RGB to HSL. I used arrays of emojis arranged by brightness and saturation, and they were HSL-based for the best matches of average pixel colors with the emojis.

In this article, we’ll study functions that will be useful for converting both opaque and alpha-enabled color values. Modern browsers currently support the color spaces RGB(A), hex, and … Read article “Converting Color Spaces in JavaScript”
