comark/colors/invalid-color · Write palette colors in a form it can draw

A palette draws hex, rgb(), hsl(), hwb(), lab(), lch(), oklab(), and oklch() colors. It doesn't read named colors such as teal, or var() and color-mix(), whose color depends on the page, so a line with one of those is left out.
