site titel on mobile version different

[chrissy]

Hi,
in the mobile view, my “Site title” is blue or purple. In the iPad or desktop version it is black as it should be. How can I change it so that the site title is also black in the mobile version? The site title is an HTML code in which I have also specified black as the color.
<font color="000000"><font face="Helvetica"><font size=7><b>CHRISTIN </br> BÜTTNER</font></b></font>

Even if I click on “hide” in the site title, it does not disappear!

go to customize → mobile → mobile site title

it may be better to not use a html code for this but just to use the normal lay theme settings in the customizer to set this up
