No, but if the overwhelming majority of viewers see a light blue
background, it would make a lot more sense to have a light blue
background on the formula than a white background. Both will look
wrong on some style, but they may as well at least look right on the
default style.
If we want to skip transparency and just allow changing the background
to any other solid color, it looks like it's pretty easy for a
bare-bones fix: just add this as line 736 (in r59357) of texutil.ml:
| "\\pagecolor" -> (tex_use_color (); LITERAL (TEX_ONLY
"\\pagecolor"))
Then people can use the "\pagecolor{...}" command to change the
background just as they can use "\color{...}" now to change the
foreground color (see [[m:Help:Math#Color]]).
