Changing Header and Search Button Colour

Hi There I found the thread below but don't know where to find the colour codes: Login to your WordPress admin section. Go to Appearance => Customize => Additional css and add the following css to change the color of the header. .site-header { background-color: #color-code; } Note: change #color-code to the desired color code. You can search for color code and replace with your desired color. To remove search function add the following css. #primary-search-wrapper { display: none; } Let me know if you have any more issues. Regards, Tikaram Assistance please?
