1. For the menu logo pls add the following custom CSS in themeoptions.
#site-logo a img {
max-height: 55%;
max-width: 55%;
}
You can change the percentage width and height accordingly.
Also in themeoptions – site logo tab you can set margin , font , color etc
2.For changing the skin color pls go to theme options, general tab – find theme skin and change the color to cyan and save the changes.
