Dark Mode Check — email dark mode preview

You build an email, it looks right, and then someone opens it in Outlook with dark mode on and the logo is gone. Dark Mode Check shows you that in Figma, while you can still fix it.

Select your email frame and click Preview and check. The plugin draws a copy next to the original, recolored the way dark mode clients recolor HTML, on a dark canvas. Then it tells you:

Which logos and icons disappear, because pictures keep their colors while the background behind them changesWhich pictures will sit in a box, because they have the old background baked inWhich text drops below a readable contrast against its new backgroundTwo behaviors are covered, taken from Litmus's and Email on Acid's dark mode guides, and the plugin shows the date they were last checked:

Partial invert (Outlook on the web, iOS, Android and Mac, and Gmail on Android): light backgrounds go dark, dark text goes light, dark backgrounds stay.

Full invert (Gmail on iOS, Outlook on Windows, Windows Mail): every color flips, dark backgrounds included.

Gmail on the web, Yahoo, AOL and Apple Mail show the email as designed, so there is nothing to preview for them.

Vectors and image fills count as pictures. Filled frames, rectangles and text count as HTML color. If the plugin guesses wrong for a layer, tag it and the plugin follows the tag.
