Hi Tom,
Problem seems to be solved.
What i did was to do what you told me.
However, being in these options, on the right hand side i had my website page.
Colors weren’t chaning there after changing the color code. As before. No influence.
Nevertheless, pushed publish after keeping the color code set. As before. No influence.
Went to another screen, so not the one on the right hand side of the options to change color, but a new one, and colors had changed.
Thank you, for bringing me to the beginning of the solution.
Martin
