background color fixed header top

Goodmorning, I want to chance the background color of the fixed header. I've added the following to my custum CSS: .page .entry-title { display: none; } #page {background: #b8c0d6; } #fixed-header-top {background: #b8c0d6; } (the first line to eliminate the page title) Changing the color does have some effect but it's almost like its gradient because depending on the choice between dark or light site option in the color options, it does vary. But I need it to be a solid color. And I have set all the color header options and the site colors to #b8c0d6. But apart from the menu in the header, the rest of the headerarea remains either too light or too dark. Thanks in advance and have a great day, Eve
