Distribution of B/T in the UVJ color space for different redshift and B/T ranges, for galaxies with log M_★/M_⊙ > 10. Each point is colored by its B/T value in the F200W band. The dotted line shows the quiescent versus star-forming separation using Eq. (2). The contours indicate 25, 50, and 75% of the density. Bulge-dominated galaxies (high B/T) predominantly occupy the quiescent region, whereas disk-dominated galaxies (low B/T) are generally in the star-forming region of the UVJ space.
