Create a Vector of Colors with specified Hue, Chroma and Luminance in R Programming - hcl() Function

Last Updated : 15 Jul, 2025

hcl() function in R Language is used to create a vector of colors from vectors specifying hue, chroma and luminance.

Syntax: hcl(h, c, l) Parameters: h: The hue of the colour specified as an angle in the range [0, 360]. 0 yields red, 120 yields green 240 yields blue, etc. c: The chroma of the colour. The upper bound for chroma depends on hue and luminance. l: A value in the range [0, 100] giving the luminance of the colour.

Example 1:

Python3

# R program to illustrate
# hcl function

# Calling the hcl() function
hcl(h = 10, c = 20, l = 30)
hcl(h = c(5, 10, 15), c = 20, l = 30)

Output:

[1] "#5E3E3F"
[1] "#5F3E42" "#5E3E3F" "#5E3F3D"

Example 2:

Python3

# R program to illustrate
# hcl function

# Calling the hcl() function

# Analogous Colors
# Good for those with red / green color confusion
hcl(h = seq(10, 50, by = 10))

# Metaphorical Colors
hcl(h = seq(10, 60, length = 4))

# Cool Colors
hcl(h = seq(120, 0, length = 4) + 150)

# Warm Colors
hcl(h = seq(120, 0, length = 4) - 30)

Output:

[1] "#FEC7C9" "#FCC8C1" "#F9CABB" "#F5CCB5" "#F0CFAF"
[1] "#FEC7C9" "#FACABD" "#F3CDB3" "#EAD1AB"
[1] "#D5D0FC" "#AFDAF5" "#99E1DF" "#A4E2C3"
[1] "#D4D8A7" "#F0CFAF" "#FEC7C9" "#FBC5E5"
