I like this approach to offering a design system. It seems less prescriptive than many:
Designed not as a rule set, but rather a toolbox, the Data Design Language includes a chart library, design guidelines, colour and typographic style specifications with usability guidance for internationalization (i18n) and accessibility (a11y), all reflecting our data design principles.
A lovely website (or web book?) dedicated entirely to colour contrast, complete with interactive illustrative widgets.
A comprehensive guide for exploring and learning about the theory, science, and perception of color and contrast.
This is a thoughtful proposal for a browser feature from Bram. Very convincing!
A fascinating four-part series by Lisa Charlotte Muth on colour in data visualisations:
At first glance, this looks like a terrible idea. But the key is in the implementation. In this case, the implementation is truly awful.
The section on detecting “auto dark theme” is, as far as I can tell, not intended as a joke.
Mind you, this could all be a galaxy-brain idea to encourage more developers to provide their own dark mode styles. (In much the same way that AMP was supposed to encourage better performance.)
A wonderful bit of spelunking into the annals of software interfaces by Elise Blanchard.
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.
Accidental colour palettes captured in the wild.
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.
Considering how much accessibility work happens “under the hood”, it’s interesting that all five of these considerations are visibly testable.
- Think about accessible copy
- Don’t forget about the focus indicator
- Check your colour contrast
- Don’t just use colour to convey meaning
- Design in anticipation of text resizing
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.
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.
I never thought of combining the datalist element with input type="color"—it’s pretty cool that it just works!
I think these are great habit-forming ideas for any web designer or developer: a day without using your mouse; a day with your display set to grayscale; a day spent using a different web browser; a day with your internet connection throttled. I’m going to try these!
A nice standalone tool for picking colours out of photos, and generating a colour palette from the same photo.
Some excellent explanations for these five pieces of sensible typography advice:
- Set your base font size in relative units
- Check the colour of your type and only then its contrast
- Use highly legible fonts
- Shape your paragraphs well
- Correctly use the heading levels
What a lovely way to walk through the design system underpinning the Guardian website.
Bonus points for using the term “tweak points”!
Here’s a clever shortcut to creating a dark mode by using mix-blend-mode: difference.
