How can I get a Color that is x% on the way between Color A and Color B? I want the same behavior as 
animateColorAsState()
except there is no animation, I just want a fixed value that would be there, say, 50% through the animation.

Just as I finished implementing my own 😄 I looked for "lerp" on the Color class, didn't know it would just be a global function, thanks!

If you’re using your own, make sure to use the oklab color space

Any reason why the default srgb shouldn't be used? Might as well change defaults then.

sRGB doesn't interpolate colors very well, notably losing luminance
Linear sRGB is an improvement but still shows luminance/hue skews that OkLab improves upon
It's not perfect either but much much better
Compose's lerp () will use OkLab
Here's a good example:
