I’m building an app that lets the user select any arbitrary color. I then want to take that color and theme some components off of it.

Is there a way in Compose to take a color and generate a theme? Or even some lighter/darker versions of it?

This sample seems to do pretty much exactly what you're asking for <https://github.com/android/compose-samples/blob/main/Jetcaster/app/src/main/java/com/example/jetcaster/util/DynamicTheming.kt|https://github.com/android/compose-samples/blob/main/Jetcaster/app/src/main/java/com/example/jetcaster/util/DynamicTheming.kt>

Also maybe this? <https://github.com/Kyant0/m3color|https://github.com/Kyant0/m3color> I think there must be something else too which I can't find atm

In case anyone else comes across this thread, and wants to generate dynamic color schemes.

I’ve turned <https://github.com/material-foundation/material-color-utilities|material-color-utilites> (which the above m3color is based on) into a Compose Multiplatform library:

<https://github.com/jordond/materialkolor>

That’s pretty cool! Does this just generate a m3 colorScheme directly, or are the parts that just generate a palette exposed too? We use a mix of material3 colorScheme + some of our own tokens, so getting access to the underlying palette would be necessary to be able to adapt something like this fully. And I assume other people are doing the same too

It just uses <https://github.com/material-foundation/material-color-utilities/blob/main/java/dynamiccolor/MaterialDynamicColors.java|this class from material-color-utilities> to generate the color from the token which uses that libraries `DynamicColor.fromPalette()`.

But I suppose there is nothing stopping you from using `DynamicColor.fromPalette()` yourself. If you had an example of the functionality you wanted, I could look into implementing it.
