How fill color with xlslib
<p>Xlslib provide 2 methods for changing the color background of a cell:</p>

<pre><code>void fillbgcolor(color_name_t color);
void fillbgcolor(unsigned8_t color);
</code></pre>

<p>but how can i create a personal color ? (by example #EFEFEF) ?</p>

<p>Cordially,
Sylvain</p>
