A color (or texture) for the bg and add the full bg prop action where I inserted a .png blur using PShop (or similar) to give it a small focus lightning area in center, growing with browser window.
It is possible, as far as I know, to build a radial blur with fillmaster and export this as an image to import it as an image but I never gave it a try. Cool blur either linear or radial should consist of more than 2 colors (that’s my personal opinion)
Banding will always be a factor of limited color range. If you move
from light gray to white, for example, there are only so many gray
values in between to share. If you use Photoshop for this, the
gradient overlay filter has an option to add noise to the gradient to
mask this. If you’re using the gradient fill brush, then you can add a
layer above the gradient, fill it with 50% gray, set it to Hard Light
and then experiment with different amounts of noise added to that fill
layer. Very low numbers – below 2 on the scale – will give excellent
results without leaving any footprints.
Also, when saving as PNG, you must use PNG 24, otherwise you are
better off (for browser compatibility reasons) saving as GIF. PNG 8
and GIF are indistinguishable under most circumstances.

How id you not get any banding in your highlight area?
What I did was, I have a dark gray bg. In PS, I made a light gray
radial gradient. When I import it is banding. Saved as PNG.
