Summary:
The syntax for is defined as (https://www.w3.org/TR/css-color-4/#color-syntax):

<color> = <color-base> | currentColor | <system-color> 

<color-base> = <hex-color> | <color-function> | <named-color> | transparent
<color-function> = <rgb()> | <rgba()> | <hsl()> | <hsla()> | <hwb()> | <lab()> | <lch()> | <oklab()> | <oklch()> | <color()>

This diff implements in particular:

<color-base> = <hex-color>

We parse over a <hash-token> to extract a 3, 4, 6 or 8 digit long hexadecimal and parse it into a CSSColor struct representation:

struct Color {
    uint8_t r // 0-255
    uint8_t g // 0-255
    uint8_t b // 0-255
    uint8_t a // 0.0 - 1.0
}
