luts.families
Return a list of colormap families.
Call signature:
luts.families()
Help text:
x = luts.families() returns a list of family names of colormaps. The family names can be passed to luts.family to obtain the names of colormaps in that family.
See also luts.demo.
The full collection of available colormaps is shown here.
Example:

import qplot as qp

import numpy as np

qp.figure('luts.families', 4.5, 4.5)

fams = qp.luts.families()

y = 0

for fam in fams:

        names = qp.luts.family(fam)

        if len(names):

                name = names[0]

                cc = qp.luts.get(name)

                L,C = cc.shape

                qp.image(cc.reshape(1,L,C), rect=[0, y, 1, .5])

                qp.at(0, y+.25)

                qp.align('right', 'middle')

                qp.text(f"{name} ({fam})", dx=-5)

                y -= 1
