PARSEC 1 Gyr isochrone at solar metallicity with extinction, A_V, ranging from 0 to 10.0 in the CAMD obtained by adopting the different Gaia magnitudes (black dots). The 1 Gyr isochrone at A_V = 0 is highlighted by a thick black solid line. The 1 Gyr isochrone at A_V = 3 is highlighted by pink coloured lines of different shades during the red giant branch (RGB), asymptotic giant branch (AGB), red clump (RC), sub-giant (subGig), and MS phases. The red, light-blue, and green solid lines are the 1, 10, and 50 Myr Pisa isochrones at solar metallicity. The empty square and the bullet in each panel represent a star of 6930 K and 3945 K, respectively, while the blue and red arrows are the reddening vectors corresponding to A_V = 3, for these two representative stars (see text).
