I figured it out when I wondered why I never see electric stove
burners glowing read.

Start with a burner that's merely warm.  You can feel the infra-red
radiation coming off it, but the coils are black.

As the burner heats, it gives off more infra red, but the peak of the
spectrum its giving off shifts blueward, so it also gives off a little
red.  But it's very little red, and you'd have to be thoroughly
dark-adapted to see it.

As it heats further, it give off more infra-red, and more red, but
when the peak is in the red, there is a lot of orange and yellow and
green and blue in the sloping tail, just as there is a lot of
infra-red in the other sloping tail.  

Even though the peak is in the red, there's enough higher-frequency
light that you don't see a pure-red red.

Get it a little hotter and the peak goes higher and shifts a little
more, and you see a definite orange.  

We've pulled a safety device off somewhere, and this being a gedanken
experiment, the coils won't melt as the burner keeps heating and the
peak emission gets higher and bluer.  

As the light gets brighter and the peak moves into the yellow area,
the light gets paler as well as yellower, and once it's pure yellow,
it just gets paler.  And when the peak hits green, we get pure white
light, because green is right in the middle, and there is as much
long-wave radiation below it as there is short-wave radiation above
it.

Which makes me wonder why plants reject green light instead of using
it.

Still hotter, and the light starts to take on a pale blue cast.  If
it's possible for something to get hot enough to appear pure blue, I
don't want to be in the same solar system with it, and I'm not sure I
want to be in the same galaxy.
