A modern programming language that makes developers happier.

I heard <https://en.wikipedia.org/wiki/HSL_and_HSV|HSL color space> is easier to reason about, but I see nothing about it in compose packages [1] [2]. There's [3], is it OK to use it?

[1] <https://developer.android.com/reference/kotlin/androidx/compose/ui/graphics/Color>
[2] <https://developer.android.com/reference/kotlin/androidx/compose/ui/graphics/colorspace/ColorSpace>
[3] <https://developer.android.com/reference/kotlin/androidx/core/graphics/ColorUtils#HSLToColor(kotlin.FloatArray)>

Some say <https://en.wikipedia.org/wiki/CIELAB_color_space|L*a*b*> is even better. And there are some mentions of it on the ColorSpace page.

The available color spaces in Compose are at <https://developer.android.com/reference/kotlin/androidx/compose/ui/graphics/colorspace/ColorSpaces>. HSL itself is *not* a color space, much like RGB is not. HSL is a transformation of RGB within a specific color space. It is indeed easier to reason about and provides a more "natural" way to do color transformations and transitions.

And for CIE Lab* see <https://developer.android.com/reference/kotlin/androidx/compose/ui/graphics/colorspace/ColorSpaces#CieLab:androidx.compose.ui.graphics.colorspace.ColorSpace|https://developer.android.com/reference/kotlin/androidx/compose/ui/graphics/colorspace/ColorSpaces#CieLab:androidx.compose[…]s.colorspace.ColorSpace>

Thanks for corrections and links, Kirill! I had no idea about the distinction between color models and spaces.
