Chrome and Firefox do not show custom primary colour

Hi,

on my test site piano-rosenkranz.web16.hucke.net I changed the primary colour from red to green.
All items shows up correctly in all my browsers except for Firefox and Chrome where the primary colour
is always red.

Can you help me solve the problem?

Greetings,

Ulrich
