[F277W – F444W] color-magnitude diagram for our F200W dropouts. The F200W-dropout sample’s objects are shown as colored stars (UHR candidates), pea green diamond (CURION, a strong line emitter), cyan cross (stacked UHR galaxies) or gray circles (all other objects in the sample). For CURION, U-100588 and U-106373 we report 1σ upper limits. Black dots in the background represent the colors of CEERS galaxies, with shaded gray contours enclosing 50% (inner), 80% (middle), and 95% (outer) of the total CEERS source density. The F444W 5σ depth is marked as a dashed black line, while the shaded brown area represents the color-magnitude space occupied by LRDs in Pérez-González et al. (2024a, albeit such a selection also requires F150W–F200W < 0.5). Gray error bars represent the average errors for objects with colors that are not upper limits.
