G2V; can be interpreted as yellow two tenths towards orange main sequence star
The Sun is a G-type main-sequence star, also known as a G2V star. This classification places the Sun in the "yellow dwarf" category.
Alpha Centauri A is a nearby star that is in the same spectral class as the sun, which is G-class. It is the primary component of the Alpha Centauri star system, located about 4.37 light-years away from Earth.

Spectral class is a classification system for stars based on their temperature and spectral characteristics. It categorizes stars into different groups, such as O, B, A, F, G, K, and M, with O being the hottest and M being the coolest. Spectral class is indicated by a letter, with additional subtype information denoted by a number.
The O spectral class is the highest temperature class. Stars in this class are extremely hot and blue in color, with surface temperatures exceeding 30,000 K.

Spectral class Y, which is typical of "brown dwarf" stars.
Sirius is a double star. The brighter component ... the one you actually notice in the night sky ... is spectral class A1V. The faint 'secondary' component is spectral class DA2.
Eta Pegasi (Matar) is a star in the constellation Pegasus.It has a spectral type of G2 so it has a colour of yellow.Matar has the same spectral class as our Sun
A star with luminosity class VI under the Yerkes Spectral Classification System. They have luminosity 1.5 to 2 magnitudes lower than main-sequence stars of the same spectral type.
Main sequence stars that appear orange are of spectral class K that are dimmer and smaller than the Sun and have masses between 45% to 80% of the Sun's mass.
