I think we're at a time in Web design where colors have become first class citizens that deserve to have their own, semantic HTML element. This is especially true given the role and importance of color swatches in design systems today. I wouldn’t mind having a
<color> element for that. But, unfortunately, we don’t have HTML elements dedicated for colors swatches. Or, do we?
For marking up colors, Taylor suggests using
<input type=“color” disabled value=“#your_color_value”> or
<svg width=“3em” height=“3em” aria-label=“#bf1942”> (check his article out for the full code).
Taylor’s justification for using
<input type="color"> does make a lot of sense, but I have to admit I prefer the SVG way, because as far as my brain is concerned, an input is for receiving input, not displaying static information, especially considering that color type inputs don’t accept a
Why does this matter?
A photo is worth a thousand words, so let me answer that by showing you what colors of the Lonely Planet style guide color swatches looked like when Windows High Contrast Mode (WHCM) is enabled:
When HCM is activated, the colors of the operating system change to offer better contrast, and the colors are propagated from Windows High Contrast into the site’s style to ensure that the site is offering a true high-contrast experience similar to other applications on Windows.
This means that any colors that can be overridden will be overridden. Since colors in design systems are marked up as empty elements with a background color, and since WHCM overrides background colors, the color swatches in the design system disappear and their value is therefore lost.
This is why it’s important to mark colors up in a way that makes the swatches immune to such external changes. Taylor suggested two brilliant solutions that I, for one, will be adopting in all my future work. Color inputs and images are left unchanged in WHCM, so your swatches would be safe from external overrides.
Also: semantics matter.
