steps to reproduce/what did you do?

  • Set an accent color for your system (e.g. I set mine to orange on macOS)
  • Create a page with native HTML inputs (radio, checkbox, text) - here's a handy one:
  • Compare the accent color of the input with the new Proton design versus current release which uses system native input styles
  • Try this with a few accent colors

expected behavior/ what did you think will happen?

  • Accent colors are generally consistent across old and new style of inputs

actual behavior/ what actually happened?

  • For certain accent colors these inputs appear darker or desaturated. My example was the orange accent, but I notice it with green and pink as well. It's less noticeable with yellow and blue.

Stephen, here is a bug about non-native theming's widget colors. This bug was filed against macOS, but I see that Nightly's non-native theming on Windows uses a slightly more darker (blue) color than Chrome's non-native widgets. (I can't compare Nightly's widget colors with the old native theme because the old native theme doesn't use colors.)

On Windows / Android the OS accent color is not used. On GTK the accent color looks fine.

When I initially implemented it for GTK, I just followed the Highlight color
everywhere, but on macOS it makes of course a lot of sense to use
