‘Never assume anything’: The golden rules for inclusive design
Inclusive design is also future-proofing technology for everyone. Swan noted that many more developers and designers are considering accessibility issues as they age and encounter poor eyesight or other impairments.
Don’t Use The Placeholder Attribute — Smashing Magazine
A lot of the issues here are with abuses of the placeholder attribute—using it as a label, using it for additional information, etc.—whereas using it quite literally as a placeholder can be thought of as an enhancement (I almost always preface mine with “e.g.”).
Still, there’s no getting around that terrible colour contrast issue: if the contrast were greater, it would look too much like an actual pre-filled value, and that’s potentially worse.

Patterns Beyond Context · Matthias Ott – User Experience Designer
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.
How the Web Became Unreadable
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.
