There seems to be a grey default background colour that doesn't change no matter which area of the site styles we have altered. It only flashes for a second while loading, but when the page itself is white, a dark grey flash is really distracting.
We have tried altering the section background, background overlay and inset border, making them all white.
If we change the white to full transparency this grey colour shows through, so it's almost like its a background behind the background.
Does anyone have any idea where we can change this to white?
