A primer on accessible colour contrast with links to some handy tools for testing.
Suggestions for small interface tweaks.
Great advice on keeping your hyperlinks accessible.
A clever performance trick for images:
- Reduce image contrast using a linear transform function (Photoshop can do this)
- Apply a contrast filter in CSS to the image to make up for the contrast removal
This is a really intriguing book that combines design theory and programming—learn about contrast, colour, and shapes, with each lesson supported by code examples.
It’s still a work in progress but the whole thing is online for free. Yay for web books!
A plug-in for Sketch that allows you to simulate colour blindnesses and check colour contrasts.
If we describe patterns also in terms of content, context, and contrast, we are able to define more precisely what a specific pattern is all about, what its role within a design system is, and how it is defined and shaped by its environment.
Kevin writes a plea on Ev’s blog for better contrast in web typography:
When you build a site and ignore what happens afterwards — when the values entered in code are translated into brightness and contrast depending on the settings of a physical screen — you’re avoiding the experience that you create. And when you design in perfect settings, with big, contrast-rich monitors, you blind yourself to users. To arbitrarily throw away contrast based on a fashion that “looks good on my perfect screen in my perfectly lit office” is abdicating designers’ responsibilities to the very people for whom they are designing.
A nice tool for choosing colour palettes that look good and are also accessible.
A cute website that’s a call-to-arms against low-contrast text on the web.
