[theme] Improve default `primary`, `secondary` and `error` theme palette #26555

siriwatknp · 2021-06-02T07:49:24Z

follow up from #26541

close #18378: dark mode following the spec
close #18776: dark mode color contrast
closes #26288: error color contrast in light mode

https://deploy-preview-26555--material-ui.netlify.app/

The goal of this PR is to have default color palette that pass AA standard for both light & dark theme. From the outcome of #26541, it is not possible to have one color that pass AA standard for both light & dark theme. So the color must be different between mode (same shade but different lightness)

https://material.io/design/color/dark-theme.html#ui-application

Primary color

V4 ❗️

indigo[500] in default theme does not pass standard in dark mode

V5 ✅

use custom color in the docs blue[700] so that the docs does not change much and the logo looks consistent.
adjust primary.dark and primary.light close to the docs

Secondary color

V4 ❗️

pink.A400 in default theme does not pass standard in light & dark mode

V5 ✅

change to purple[500] because the docs used pink.A400 which does not pass AA standard and the color is too close to error. As far as I tried, I feel purple sit very well with the primary (blue) color.
use purple[200] in dark mode similar to primary color

Error color

V4 ❗️

red[500] does not pass standard in light mode

V5 ✅

increase the number to red[700] in light mode

Info color

change to cyan[500] (it was blue[500] in v4) to not use the same color as v5 primary color and still informative color.

warning and success remains the same.

use defaultTheme here to remove hard coded color in the test below.

I wonder should defaultTheme be exported as defaultLightTheme from @material-ui/core/styles also?

In my side project I use defaultTheme a lot and it is quite annoying to call createTheme() everytime.

The goal of this PR is to have default color palette that pass AA standard for both light & dark theme.

Was this not the case before? Listing these instances in a single place might be interesting for people that manually patched them for this purpose. Sounds like they can now remove code only targetted at patching AA ratio.

which will close #18378, #18776

Github will only close one of them. Each referenced issue/pr needs to have its own magic keyword associated

Do we include the color in the warning? If not then we can follow-up. Otherwise I'd make sure the color is included in the assertion which means we can get rid of the (potentially wrong) code comments.

2 lines was there at the beginning (1 more is added because info is changed to cyan[500], it's sound intentional that we expect the colors to falls below contrast ratio. I was confused at first about this test so I added comments at the end. Any suggestion?

siriwatknp · 2021-06-03T08:37:13Z

If you mean #26541, it is related but different. This PR fix the default color from the theme where as #26541 remove custom color in the docs.

You mean add to documentation?

No, I mean the direct thing I responded to:

The goal of this PR is to have default color palette that pass AA standard

In which instances did we not pass AA?

You mean add to documentation?

In the PR in a prominent spot so that you don't have to read through unrelated conversations to figure out what changed.

siriwatknp · 2021-06-03T10:05:03Z

Updated the description

primary color indigo[500] in dark mode
secondary color pink.A400 in light & dark mode
error color red[500] in light mode

oliviertassinari

I'm updating the PR's description, it fixes #26288 too. Regarding the contrast issue with error. See below, top down:

Our new color

michaldudak · 2021-06-04T08:15:22Z

Could we also change the background color of code? The current greenish-brown seems a bit out of place as it doesn't match anything else on page. IMO it doesn't play well with with the cyan when there's an a inside code (even though the contrast ratio is OK, it just doesn't feel right):

I propose we use the same background as in pre:

or something a bit lighter, like #333944:

in mui/material-ui#21514 pseudo classes were moved from root to content, so we no longer need nested selectors and rules need to go on content directly use Mui-focused instead of :focus also restore muiv4 treeitem label color rule to get a different color right after a click on an item.

After a quick look, we didn' customize TreeViewFinder which also uses TreeView/TreeItem so it shouldn't need the same fixing as ReportViewer. in mui/material-ui#21514 pseudo classes were moved from root to content, so we no longer need nested selectors and rules need to go on content directly use Mui-focused instead of :focus also restore muiv4 treeitem label color rule to get a different color right after a click on an item.
