- Show more similar colors by using `--hue-extent`: `select_colors -H148 --hue-extent 5 |sort -g -k8`

- Show colors opposite in hue to the reference color: `select_colors -H148 --hue-extent 5 --opposite|sort -g -k8`

- Colors with similar lightness to color `148`: `select_colors -L148|sort -g -k8`
