hex_to_name

Reverse lookup using the bundled name database. When an exact match is not
found, you can return the nearest named colour (<code>fallback = TRUE</code>, the
default) or <code>NA</code> (<code>fallback = FALSE</code>).

Provides a comprehensive 'API' for colour conversion between popular
colour spaces ('RGB', 'HSL', 'OKLab', 'OKLch', 'hex', and named colours) along with
clean, modern 'CSS' Color Level 4 syntax output. Integrates seamlessly into
'Shiny' and 'Quarto' workflows. Includes nearest colour name lookup powered by
a curated database of over 30,000 colour names.
'OKLab'/'OKLCh' colour spaces are described in Ottosson (2020)
<https://bottosson.github.io/posts/oklab/>. 'CSS' Color Level 4 syntax follows
the W3C specification <https://www.w3.org/TR/css-color-4/>.
