Add support for defining a theme color for both light & dark modes (prefers color scheme)

There’s a good discussion here (kicked off by Jen) about providing different theme-color values in a web app manifest to match prefers-color-scheme in media queries.

Building Dark Mode | Product Blog • Sentry

Robin makes a good point here about using dark mode thinking as a way to uncover any assumptions you might have unwittingly baked into your design:

Given its recent popularity, you might believe dark mode is a fad. But from a design perspective, dark mode is exceptionally useful. That’s because a big part of design is about building relationships between colors. And so implementing dark mode essentially forced everyone on the team to think long, hard, and consistently about our front-end design components. In short, dark mode helped our design system not only look good, but make sense.

So even if you don’t actually implement dark mode, acting as though it’s there will give you a solid base to build in.

I did something similar with the back end of Huffduffer and The Session—from day one, I built them as though the interface would be available in multiple languages. I never implemented multi-language support, but just the awareness of it saved me from baking in any shortcuts or assumptions, and enforced a good model/view/controller separation.

For most front-end codebases, the design of your color system shows you where your radioactive styles are. It shows you how things are tied together, and what depends on what.

A handy tool for getting an overview of your site’s CSS:

CSS Stats provides analytics and visualizations for your stylesheets. This information can be used to improve consistency in your design, track performance of your app, and diagnose complex areas before it snowballs out of control.

Sass Color Functions in CSS | Jim Nielsen’s Weblog

I’m not the only one swapping out Sass with CSS for colour functions:

Because of the declarative nature of CSS, you’re never going to get something as terse as what you could get in Sass. So sure, you’re typing more characters. But you know what you’re not doing? Wrangling build plugins and updating dependencies to get Sass to build. What you write gets shipped directly to the browser and works as-is, now and for eternity. It’s hard to say that about your Sass code.

Better Image Optimization by Restricting the Color Index – Eric’s Archived Thoughts

A great little mini case-study from Eric—if you’re exporting transparent PNGs from a graphic design tool, double-check the colour-depth settings!

I’d been saving the PNGs with no bit depth restrictions, meaning the color table was holding space for 224 colors. That’s… a lot of colors, roughly 224 of which I wasn’t actually using.

Limiting input type=”color” to a certain palette (from an image) | Christian Heilmann

I never thought of combining the datalist element with input type="color"—it’s pretty cool that it just works!

Unraveling The JPEG

A deep, deep, deep dive into the JPEG format. Best of all, it’s got interactive explanations you can tinker with, a la Nicky Case or Bret Victor.

Oh Hello Ana - Colours of 2018

I love this idea of comparing human colour choices to those of a computer:

I decided to do two things: the top three most used colours of the photo decided by “a computer” and my hand picked choices. This method ended up revealing a couple of things about me.

I also love that this was the biggest obstacle to finding representative imagery:

I wanted this to be an exciting task but instead I only found repeated photos of my cat.

I don’t really understand what this colour tool is doing or what it’s for, but I like it.

Dark theme in a day – Marcin Wichary – Medium

On Ev’s blog, Marcin goes into great detail on theming an interface using CSS custom properties, SVG, HSL, and a smattering of CSS filters.

I was kind of amazed that all of this could happen via CSS and CSS alone: the colours, the transitions, the vectors, and even the images.

V6: Color | Rob Weychert

Go deep, deep down the rabbit hole of Rob’s brain in all its colourful glory. Seriously, this is simultaneously a great write-up of how he came up with his site’s lovely colour scheme(s), and it’s a terrific primer on colour theory and why the HSL value in CSS is so, so wonderful!
