Convert a colour vector to greyscale

A thin wrapper around color_desaturate() with amount = 1 – every colour's HSL saturation is dropped to 0, leaving only its own lightness. This is a plain HSL desaturation, not a perceptual (luminance-weighted) greyscale conversion – two colours with very different perceived brightness but the same HSL lightness (e.g. a saturated yellow and a saturated blue) convert to the same grey.

Usage

color_greyscale(color)

Arguments

color

A character vector of colours.

Value

A character vector of hex colour strings, the same length as color.
