Yes, you can override heatcanvas.bgcolor by an RGBA array before rendering. For example:
heatcanvas.bgcolor = [100,0,0,255]
On changing background color, You may also want change default color schema. Just pass a function to render
which takes a value (in range [0,1]) and returns an HSLA array for that value.
from heatcanvas.
On changing the color schema: can you explain a little more how the default works? In other words, if I just push in some values at a particular location, what determines the color at that exact location, and what determines the color and thickness of the concentric blobs around that location? Also, what are the range of values that the render function expects (i.e. between [0,1], [0,255] etc.)?
Thanks.

You can not define a color for a particular location, but a particular value, by overriding the default color schema function. And the default function looks like this: https://github.com/sunng87/heatcanvas/blob/master/heatcanvas.js#L153
For the range, consult the documentation: https://github.com/sunng87/heatcanvas#3-render-the-map
