Change this Blue colour

Hi Victor,

For reference, can you provide the link to the site in question?

You may use the Private Information field for this: https://docs.generatepress.com/article/using-the-premium-support-forum/#private-information

Here it is Twendesasa.com- check out on mobile version

Thank you!

The color when typing on the Search Bar is already Black from my end. To confirm, do you still need assistance with regards to this?

As for the second inquiry, can you try adding this in Appearance > Customize > Additional CSS?:

@media (max-width: 768px) {
    .site-branding {
        flex-basis: 100%;
    }

    nav#site-navigation.has-active-search {
        flex-basis: 50%;
    }
}
