Extending color space

Humorous make use of css functions rgb and hsl at the moment, extending color space might be a little more complicate.

Custom CSS function (which is not available)
You can create a custom css function, for example brgb(r, g, b) to display your new color space
Mapping color space to rgb color space
You can provide some mapping to rgb, and it will work fine
Not a new custom color space, just rgba(), hsla(), hwb(), lab(), or lch()
It will work right out of the box
