Transparent header - text color

Site URL: https://www.momentephoto.com

Hi,

I have some troubles with header of my website. I would like to set transparent header because on page with my work (called Naše práce) there is a photo begining on the very top of the page. On this site everything looks fine but the problem shows when I go to the homepage, where is photo set as inset so it has white edges like background of the page and there the transparent header doesn´t work. On the homepage I need the text of the header to be black but it´s light gray (it was even white before but I probably changed it somehow and don´t know how) but I can´t find any option how to change it if the header is transparent. Is there anyone who could help me, please?

    fill: black;
}

Thank you very much, Tuanphan. You are a lifesaver!
