Projected axis ratio (q) observed in JWST/NIRCam-F444W against U − V (upper panels) and V − J (lower panels) colors in four redshift bins. The color-coding shows the color gradient computed as the difference between the color between 1−2 R_e and 0−1 R_e. We only show quiescent galaxies with stellar mass M_★ ≥ 10^10.5 M_⊙. In the lower left corner, we show the median uncertainties on the rest frame colors and axis ratios and the Spearman correlation coefficient between the axis ratio and the color, and in the right corner, we show that between the axis ratio and the color gradient.
