The colour of the background

Hello again,

I have problem with the colour of the background. How to make that colour was darkened but in green or blue ? Thank you in advance for help.

Hi,

Are you referring to the overlay of the header image? Use this and adjust as needed:


.header-image::after {
    background-color: #62a0bd;
    opacity: 0.9;
}

Thank you Vlad, now all is working. You helped me a lot.
And one question, how to get back to the original overlay ?

Not sure I follow. You would just remove the code I gave you.
