Usage of the hwb() color function has seen a decline in recent years, leading to questions about why it is not as popular.
hwb() is a color function in the sRGB color space, offering a way to specify hue, whiteness, and blackness.
While hwb() is considered more intuitive than hsl(), the latter has been around for a longer time and is more widely used and familiar to developers.
Alternative color functions like lab(), lch(), oklab(), and oklch() offer more color options and perceptual uniformity compared to hwb(), suggesting they might be better choices for color manipulation.
