Color–color selection of LRDs described in Barro et al. (2024a), originally defined for galaxies at z > 4, applied to the inner regions of our sample at z > 4 (shown in red). For galaxies at z < 4, the same rest-frame colors are probed by shifting the bands accordingly (shown in blue). Contours represent the 25%, 50%, and 75% density levels for each distribution. The applied color correction is indicated by a thick black line, with an average shift of ≈0.2 mag.
