Hi
You can download the module from template download page here : https://www.joomlart.com/member/downloads/joomlart/joomla-templates/ja-helple

For the logo BG color it is using bg-primary class that is defined in the Layout options > Edit header section > edit header-1 code
http://prntscr.com/17dvwr4
find bg-primary You can replace it with support type classes : /index.php/pages/joomla-content/typography
Or create own custom class

You logo is not transparent its using Text type logo not image.

The logo is not blur its due to the Font family applied on it. This is style of font
you can override it via custom css using this code

 .navbar-brand.logo-text {
    font-family: 'Anton';
}

Hi
You should change the logo first time. From text to image.
The Logo settings are present under Site configuration > Logo Settings.
Like it's shared in the documentation https://www.joomlart.com/documentation/joomla-templates/ja-helple
Once done kindly let me know for image size part.

Hi
The red color is coming from the bg-primary class in the header code.
open template style > edit layout > Edit header code : http://prntscr.com/17y5i6t
Find : bg-primary and remove it http://prntscr.com/17y5mbb
And define own custom class to make a different bg color.

Hope it helps.

Hi
Add this code in custom css and set max width

#t4-header .t4-logo-header .logo-image .logo-img {
    max-width: 80px;
}

Your logo image size should be greater or equal to the value you set in custom css.
