Our Sun has a spectral class of G2V.
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.

G2V; can be interpreted as yellow two tenths towards orange main sequence star
Our Sun belongs to the G spectral class, specifically classified as G2V. This classification indicates that it is a yellow dwarf star, characterized by its surface temperature of around 5,500 degrees Celsius (about 5,800 Kelvin) and its moderate brightness. The "V" denotes that it is a main-sequence star, undergoing hydrogen fusion in its core.
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.

Spectral class Y, which is typical of "brown dwarf" stars.
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
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.

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.
