You can set the Background Color using a color picker pop-up. Click on the "Background Color" setting then click the preview box to open the color picker.
You can enter a
HEX value and adjust its hue and transparency with the sliders by default.
When adding a background color it will be fully transparent, just move the slider all the way to the right to make it fully opaque.
HEX color values are six characters long, you can have two additional characters (as a
HEX value) in this option to set the color transparency.
00 would be fully transparent while
FF would be fully opaque (although not required by default).
You can also use the
RGBa color method, or the
HSLa color method to enter the color (and adjust with the sliders as needed). Also to note, changing between color methods will automatically set the appropriate values for the color currently being used.
Please keep in mind not all colors are considered "web safe" although most will render very close to those supported by modern web browsers if there is not an exact match.
See W3 Schools CSS Legal Color Values for more in-depth details on color methods.
