No stars blue? A star's colour depends on it's temperature. A blue star must be very hot in order for it to glow blue. All stars in the main sequence sre only hot enought to glow yellow, not hot enought to glow blue.
yes
The HR diagram does not reference stars on their way to the main sequence, only during or after.
The temperature of main sequence stars can vary quite a bit.
Beacuse they are dimmer, but they're also bigger than the main sequence stars.

There are billions of stars that are not on the main sequence.
The smallest stars in the main sequence are the stars with cooler surface temperatures.
Of the stars you can see from Earth, 90% are in the main sequence.
"main sequence" is the tern.
Most of the stars in the universe are found on the main sequence. Stars fall off the main sequence when they begin to die.
