Wow, that was fast! Thanks, echicken.

I was looking around online and experimenting with a bitwise calculator, and I
ended up doing something like this:

// Use bitwise AND with a mask to get the four rightmost bits.
// dec 15  |  bin 00001111  |  hex 0xf
var fg = theAttr & 15;

// Use bitwise AND with a mask to get the four leftmost bits.
// dec 240 |  bin 11110000  |  hex 0xf0
var bg = theAttr & 240;

I think it's working, but I have other issues in my code to sort out before I
can say 100%.

Then I'm doing fg = fg & 7 to change high colors into low equivalents.
