It was not changing the colors since e3e6c034 and had an overflow on
`options->devices.size()` since 0f4ddd16 causing options not to be applied
Second issue was a bit trickier as it was not reproducable when using a
debug build. It seemed like `std::vector<DeviceOptions> devices` had an
overflow. I saw a bunch of warnings regarding comparison with implicit
cast so I figured I'd fix that first and see if it makes a difference.
Turns out it did and fixed the issue.
While toying around, I also noticed that `throw` didn't seem to work,
causing crashes later in the program. It turns out the catch-all clause
`catch (...)` is not necessary matching a `throw NULL` expression as it
might be of type `int`. The solution is to use `thrown nullptr;`
instead.
