I guess this would be the WebUI version of Issue 850098, so I won't dupe it. groby@ do you know who I could coordinate with on the WebUI team?

Clearly, dpapad wears a buzzer hotwired to WebUI bugs. (And he's the contact to coordinate with)

FYI, we have some initial mocks for WebUI dark mode from UX and soon will have an exact spec as well.

I am going to mark this as a Feature request for now, and will share any updates on this bug.

 Issue 900639  has been merged into this issue.

Assigning to markchang@ for now, since the deduplicated bug was already assigned.

I can be the engineering PoC for now :)

Dark Mode: split out TestNativeTheme as a separate class/target

There was a handy dandy testing version of NativeTheme in
view_unittest.cc that I'd like to reuse in upcoming unit tests for WebUI
Dark Mode support (https://crrev.com/c/1354685).

Dark Mode / WebUI: make TestWebUI auto-register message handlers

This makes test code easier to write and understand and is also what the
"prod" WebUI class already does.

This is loosely related to Dark Mode support, as I discovered this
difference in behavior while working on unit tests for this work.

Dark Mode: make a testable WebUIDataSource for unit tests

There was no easy way to get at the set load time data keys/values nor
the $i18n{} placeholder strings.  My upcoming work for dark mode
requires a key be set whether or not dark mode is enabled or on.

I'm adding TestWebUIDataSource in hopes that it's more generically
useful, as TestWebUI has been.

Example use here: https://crrev.com/c/1354685

Dark Mode: split color variables to top of shared_vars_css.html

This allows us to set light/dark mode variants at the top and reuse them
throughout the file (and elsewhere, in some cases). I also made use of
some of the variables in some cr_elements (i.e. toolbar, menu, etc.).

I also start looking at some of the pages with --force-dark-mode on and
fixed small stuff to make them readable. Generally I wanted to make
cards the right color and text readable. Various pages (i.e. settings,
downloads, history, bookmarks) look terrible but are actually dark now.

Dark Mode: add a better way of creating opacity variants of colors

Previously, there were things like:

  --some-color: #010203;
  --some-color-opacity-X: rgba(1, 2, 3, X);

Which is a bit inflexible and leads to a bit of redundancy. Instead,
let's use this syntax, which allows minting an arbitrary number of
colors with var() + rgba() syntax:

  --some-color-rgb: 1, 2, 3;
  --some-color: rgb(var(--some-color));
  /* later ... */
  color: rgba(var(--some-color-rgb), X /* any opacity */);

but this gets us closer to Namrata's mocks.

Because of an unfortunate miscommunication, I assumed colors in the
WebUI Dark Mode spec were from the Material Design (MD) palette instead
of the Material Modern/Refresh (GM2) version. Whoops.

There's probably a lot more colors to update soon.

Dark Mode: fix a bunch of wrong colors

When I first started working on this project, the spec had a bunch of
"GG 500" and "GB 300", which to me meant the Material Design colors.

But there's actually a new version of the color palette (GM2) with the
same names, which is a bit of a bummer.

Even more confusingly, various variables in the code use the same naming
scheme as Material Design but for GM2. Ex:

  --google-grey-100 -> Material Design
  --google-grey-200 -> GM2

There are -refresh version of colors, which mean the GM2 equivalent.

  --google-grey-500 -> Material Design
  --google-grey-refresh-500 -> GM2

This is fairly nuts.

Anyways, cuz I'm still mildly hoping WebUI dark mode makes Chrome 73, I
grepped for all the places that use [dark] and then looked for possibly
wrong colors. Here's the command I used:

  $ git gs '\[dark\]' -l | xargs egrep -l \
    '\-\-google-(green|red|blue|grey|gray|yellow)-[1357]00'

And updated the files I found.

I also added some new GM2 equivalents (more -refresh colors) and ran
third_party/polymer/v1_0/rgbify_hex_vars.py on it to produce the -rgb
versions.

Dark Mode: update paper-icon-button-light's ripple opacity

The only real change here is +25% effective opacity by raising both the
opacity of the <paper-ripple> (60% -> 100%) and the <div class="ripple">
inside of it (25% -> 40%) as the spec calls for 40% of the text color.

Dark Mode: stop light mode styles from bleeding into dark mode buttons

Light mode, secondary paper-button:hover border-color was coming through
because an equivalent variable wasn't being defined for dark mode.

It's very hard to see, but I think the same story was happening for
primary paper-button:active box-shadow.

Dark Mode: update Bookmarks page folder icons and selection colors

Folder icons:

Use -webkit-mask-image instead of background-image allows us to change
the color of the fill dynamically. This means we can create light/dark
with the same .svg.

Selection colors:

Dark mode needs more code for selection (than light mode) because the
specs call for inverting the background to light blue (so the text and
icons must be flipped to dark on light, whereas they're typically light
on dark).

I also strove to generally simplify some border/background color logic
by using currentcolor, which lets other properties use the text color
as a value.
