CZR of the GCs. Each panel shows the spectroscopic metallicities versus HST F606W − F814W colour and predictions from the EMILES models colour-coded by age. From left to right: Colours from Paper I, Trujillo et al. (2019), van Dokkum et al. (2022a), and synthetic colours derived from the MUSE spectra directly. In the right panel, we also include the Fornax3D GC sample from Fahrion et al. (2020a).
