No. Only the most massive main sequence stars are blue. Because blue stars are short-lived compared to other stars they are almost invariably young. Less massive stars live much longer, so only a fairly small portion of them are so young. For example a star like our sun can be expected to remain on the main sequence for about 10 billion years, if the rate of formation of such stars is constant then you can expect 1 in every 1,000 such stars to be in their first 10 million years on the main sequence.
As the HR diagram shows, the hottest stars on the main sequence range from 30,000K as blue-white stars to about 3,000K as redish stars.
The most massive main sequence stars are typically blue in color, due to their high surface temperatures. These stars are known as O-type stars and can be tens of times more massive than the Sun.
Blue stars are more luminous than other main sequence stars but not necessarily brighter than giant and supergiant stars.
"main sequence" is the tern.
About 90% of all stars are main sequence stars, including our Sun. These stars are in the stable phase of their lifecycle, where they fuse hydrogen into helium in their cores. Main sequence stars are the most common type of stars found in the universe.
No. They have the lowest temperatures on the main sequence. The hottest main sequence stars are blue.

Fairly young ones.
Yes. Amsonia hubrichtii is the scientific name of a blue star. Blue stars are part of the Main Sequence stars.
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.

There are billions of stars that are not on the main sequence.
As the HR diagram shows, the hottest stars on the main sequence range from 30,000K as blue-white stars to about 3,000K as redish stars.
The smallest stars in the main sequence are the stars with cooler surface temperatures.
Main sequence WIMP burners look much like protostars link the paradoxically young OB stars found at the galactic centre with WIMP burners.
