Alpha channel was set to 0 anyway, so I just used transparent color instead.

I wonder what is the alternative for alpha/lighten/darken utility functions when using CSS variables?
For alpha, something like this should work, right?
'rgba(${theme.vars.palette.primary.mainChannel} / 0.5'
But then, not every color in the palette has a xxxChannel representation.

I believe we observed a similar problem in mui/mui-x#6784

'rgba(${theme.vars.palette.primary.mainChannel} / 0.5' this is correct, and yes, we are generating channels for some colors not all.

What about this case?
'rgba(${theme.vars.palette.primaryDark[900]} / 0.5)'The above won't work, and there's no channel for primaryDark[900] color.

rgba(${theme.vars.palette.primaryDark[900]} / 0.5)
Where is it? The gradient looks fine to me.

Is this intended to be"Safari on iOS", or "Safari and mobile device(s)", in which case, which?

Initially, I wanted to use 'transparent', but then I noticed this comment and copied it:
In https://css-tricks.com/thing-know-gradients-transparent-black/ it says it's Safari - both desktop and mobile.
But it's an article from 2017 and using 'transparent' doesn't seem to make any difference in Safari 16:
Screen.Recording.2022-11-10.at.19.47.41.mov
I'll update the comments to only mention Safari and also link to the article above.

Actually, using rgba(255,255,255,0) everywhere didn't look good in Safari. I'll push a fix

It looks like this pull request indicates that the rgba settings do with for safari. If that's right then I think this is good to go. Does rgba still not work for mobile devices?
I like the choice to define the transparent setting above and reuse it. Helped clean things up.
It's not about rgba not working, it's about Safari treating transparent black and transparent white colors differently - see https://css-tricks.com/thing-know-gradients-transparent-black/ |
