[Feature Request] support colors

[J-Sek]

Currently the preset lets me drop all $utilities: false, but I need to keep $color-pack, use any preset for TailwindCSS or write my own rules.

Not a hard requirement, but we could brag about making bundle 9.4x smaller (5.9x smaller gzip).

entry bundle in Nuxt	Raw size	GZipped
default size (excl. icons)	261.72 kB	33.38 kB
without utilities	59.20 kB	10.17 kB
without colors and utilities	27.58 kB	5.65 kB
