What color are small cool stars?
Small cool stars, such as red dwarfs, are typically red or orange in color. This is because their surface temperatures are relatively low, causing them to emit more red and orange light compared to other colors.

Red giants.
Do blue stars and red giant stars have similar brightness values?
Blue stars are generally much brighter than red giant stars. Blue stars are very hot and luminous, emitting a larger amount of energy compared to red giants, which are cooler and typically less bright.
Majority of stars are small cool type-M stars?
Correct. M-type stars on the main sequence are called red dwarfs.
